A photograph featuring a person with long hair in a ponytail held down by a headband that looks like a chain and wearing blue rimmed protection glasses that reflect the room, looks at a panel carefully. Behind the panel is a friction stir welding spinner, which looks like a big hydraulic cylinder with a drill bit at the end and there is a plastic hose attached. Behind this, a red, metallic workbox and green wall is slightly out of focus. Must be read in the voice of the movie Voice-Over artist: “In a world where dissimilar metals cannot be joined, one path stands above the rest…”

Friction Stir Welding: The New Frontier in Welding

In 1991, an elegant new way to weld metals revolutionized the world. The process known as friction stir welding (FSW) moved welding out of the Stone Age and into the technology age, allowing precise, mess-free welding.

Friction stir welding is a solid-state joining process where a rotating and traversing FSW tool generates sufficient frictional heat along a joint between two metals to form a weld. It can be considered a “green” approach to joining since an external heating source is not needed and is more environmentally friendly than other methods since neither a flux nor a shielding gas are required.

There are several strength, speed, consumption, and cost benefits associated with friction stir welding. Many of these advantages are due to the fact that there is no microscopic melting during FSW, so the process is free of problems associated with traditional welding, such as porosity, lack of fusion, and change in material.

In this blog, we will discuss a remarkable benefit also associated with FSW: the ability to weld dissimilar aluminum alloys.

Welding of Dissimilar Alloys

Industries such as aerospace, military, transportation, manufacturing, and cargo ship production have a pressing need for welding dissimilar metals. Welding, instead of riveting, joints can produce significant cost savings while reducing the weight of their vessels or constructions.

However, the welding of dissimilar alloys poses quite a conundrum. The different chemical and physical properties of dissimilar alloys can cause havoc as metals flow into each other during a conventional welding process.

For example, the different melting temperature, thermal conductivity, coefficient of linear expansion, and heat capacity of steel and aluminum causes their joint to be brittle whenever they are fused.

Friction Stir Welding: Easier Welding of Aluminum Alloys

Fortunately, FSW has proven to be an effective way to join similar and dissimilar aluminum alloys. In contrast to traditional fusion welding, FSW is free of the problems associated with fusion welding of dissimilar alloys, like porosity, segregation, and liquation cracking. For these reasons and more, higher joint quality is a characteristic of this approach.

FSW’s ability for welding dissimilar aluminum alloys at an industrial level is aided by being a solid-state welding technique.

The Future of Friction Stir Welding and Dissimilar Alloys

 

Despite FSW’s success with aluminum, not every combination of metals can currently be welded by FSW, including some aluminum alloys. The formation of intermetallic compounds lowers weld quality.

Monumental efforts in research and development are being applied to the achievement of these FSW goals. This involves a lot of trial and error with spin speed, spin head and pin materials, and joint configurations.

Other options, such as submerged friction stir welding — submerging or having water run over the welding zone — might solve common problems associated with dissimilar welding alloys. The water helps extract heat from the joint, decreasing grain size and increasing tensile strength.

In other research areas, techniques such as friction stir knead welding have been used successfully to weld together very thin aluminum sheets with steel. The distinguishing feature of this variant of FSW is that it does not use the pin portion of the rotating tool.

Taber Extrusions: The Shape of Endless Possibilities Since 1973

2022-02-03T22:46:16+00:00January 3rd, 2022|

A billboard-style, graphic presentation featuring various-sizes of rendered aluminum extrusions, with the words “Taber Extrusions, The Sky is The Limit” in large bold silver lettering and a caption that reads, “complex aluminum extrusions for virtually any application,” an inverted gold triangle logo next to the word “Sky” has a background of mountains behind it all.

Taber Extrusions has extrusions in the name, but it’s really a full-service aluminum extrusion company. Taber controls it all, from the casting of the billet, the extrusion process, fabrication, and finally, the logistics.

Taber possesses a commitment to meeting and exceeding customer expectations by providing both products and customer service levels that are of the highest quality. This commitment is at the core of their operating philosophy.

Taber Extrusions History

Taber Extrusions was founded in 1973, when the Taber family acquired an aluminum extrusion plant in Russellville, Arkansas from Dow Chemical (which had originally built the plant in 1970). National Material Company L.P. (NMLP) later purchased the company in 1976. The Arkansas facility was originally dedicated to the production of specific military-related, large, wide, and long extrusions for the U.S. government.

A graphic showing an outline of the state of Arkansas, with a red map pin and Taber’s gold inverted triangle logo marking Russellville. The words “The Shape of Endless Possibilities” are to the right of the map.

Taber’s Russellville facility houses the largest rectangular aluminum extrusion press in North America, which uniquely positions Taber to extrude super-wide shapes – much more comprehensively than is possible with traditional round containers. This rectangular container allows them to supply some of the industry’s widest, most complex, multi-void hollows.

In 1995, the Gulfport, Mississippi facility was acquired in response to the growing need in the domestic market for aluminum billet products. Taber added 7″ billet molds to their existing extrusion billet casting profile.

With the intention to expand even further, in 2015, Taber upgraded the Russellville fabrication facility even more. By 2017, Taber’s aluminum cast house expansion was completed and acquired 7″, 9″, 11″, 16″, 20″, and 10″ x 20″ rectangular billet molds.

Taber completed the relocation and start-up of its micro-extrusion press lines in 2018. This greatly expanded their supply possibilities with extrusion solutions, programs, and services. Taber’s newest ultra-precision extrusion manufacturing lines have a product envelope with a circle size of 3 inches or less and a weight per foot of 1 lb. or less. The micro-extrusion presses differ from traditional extrusion presses in that they can produce extrusions with a wall thickness of 0.010 inches and tolerances of +/- 0.001 inches. Designers and engineers can use these micro-extrusion production centers to develop profiles that would otherwise be impossible to extrude using conventional presses.

In April 2019, Taber held a groundbreaking ceremony to announce its newest in-house FSW capability, making them a vertically integrated supplier of FSW panels and assemblies never before seen in North America.

Congressman Steve Womack described how he sees Taber’s role from both a local and national perspective:

“The expansion of an existing company such as Taber Extrusions means a lot more than the location of a new company. It means that Taber is in the right place and has what it needs to succeed. Taber plays an important role in the defense of our nation with products that are an asset to our defense capabilities.”

“This was an obvious next-step for Taber,” said Jason Weber, V.P. of Sales and Marketing, in an article by Light Metal Age Magazine. “The company was founded in 1973, and never stopped diversifying, adding new capabilities, and technologies. We are known for aluminum extrusions, fabrication, billet casting, ultra-precision extrusions. Friction stir welding was going to happen eventually.”

As for the most recent addition to Taber’s extrusion capabilities, they announced the Haas VF-12 CNC. This one-of-a-kind machine allows Taber’s top engineers to design optimal extrusion shapes using specialized software to have them made within this “self-contained factory,” all in one precise and effective process.

Weber had this to say about their 2021 machining center expansion

We will continue to invest in technologies that provide the widest scope of services in the aluminum extrusion industry. The Haas VF-12 CNC machine is yet another example of our willingness to invest and deliver the widest scope of services across the aluminum extrusion continuum.”

Taber Aluminum Alloys: Straight to You!

2020-05-12T17:58:44+00:00March 11th, 2020|

Aluminum billets being casted at Taber Extrusions’ upgraded aluminum casthouse in Gulfport, Mississippi.

Here at Taber, we’ve listened to market demands by updating our Gulfport, MS. casthouse, and we are now proud to offer top quality aluminum alloys made in the U.S.A. delivered to you within a short lead time.

From Aluminum Alloy to End Use

Aluminum billets (also referred to as “logs” or “ingots”) are not of practical use until they have been formed into more functional shapes and sizes. While they have already been put in the furnace, they still require a series of shaping and molding procedures such as hot and cold working, milling, and cutting.

Aluminum billets are considered fresh and raw, and they must undergo a series of manufacturing processes before they can be used for various purposes. Billets are made by means of freezing molten liquid and are later exposed to extremely low temperatures in order to allow the metal to take shape and solidify in chemical structure. The temperature manipulates the metal’s physical properties and tones its strength and durability. The subsequent processes provide the metal’s curved mold design, so it can fit inside the allotted spaces provided by other machines, which complete finishing procedures.

Proper casting is important, as it determines the quality of the product upon going through the final processing stages. These stages influence the billet’s strength and flexibility. The billets undergo a number of tests before they are sold.

Aluminum Extrusion Leader Taber Extrusions Looks Ahead

2020-02-01T20:39:14+00:00February 1st, 2020|

“2020” written in shiny, silver-colored metal – with the inverted gold Taber Extrusions logo positioned underneath.

As Taber Extrusions launches into 2020, we thought we’d take a look back at the last several years and the many ways Taber has progressed within the aluminum extrusion industry. Among many changes, Taber added an upgraded casthouse, expanded into micro extrusions; received various awards, began friction stir welding, and brought on a new business director. This has been a very exciting time, and we invite you to learn more about the innovations that are shaping endless possibilities in 2020 and beyond.

Aluminum Casthouse

Not long ago in 2017, Taber upgraded to their aluminum casthouse in Gulfport, MS. which integrates casting, extrusion, and in-house fabrication services. With this upgrade, Taber opened up opportunities in a variety of markets, with the sale of cast billet to outside extruders.  With this casthouse, Taber is targeting aerospace, automotive, and defense industries, all of which utilize aluminum at an accelerated rate. Taber’s new products are suitable for current and future U.S. infrastructure projects, such as the construction and improvement of bridges, decking, flooring, and railing for mass transportation projects.

Partnering with Almex USA, Taber developed a customized solution to meet Taber’s unique requirements and specifications. Almex supplied new equipment, including a casting line with a degassing and melt purification system, billet and slab tooling, automation technology, and a complete homogenizing line, as well as a new cooling water system.

Benefits to Taber’s aluminum casthouse upgrade:

  • Increased Production. The CASTRIGHT II™ casting machine and new billet and slab tooling stations were adapted to fit the circular pit, and the casting tables were modified to have an oval shape with unique headbase configurations. Excel™ and Optima™ billet mold systems were installed for various sized billets. The quantity of billet produced with each cast has been enlarged, allowing increased production per drop.
  • Quality Control. A large part of Taber’s consideration during this upgrade was quality control. Taber now has a level pour (or, hot-top) mold table distribution system and a way to optimize mold lengths for consistent billet quality. Taber’s goal was safety and alloy versatility for high performance and yield, from conventional to the most demanding alloys. For the larger diameter aerospace grade products, Almex installed specialized water wiping technology in order to manufacture difficult to cast materials without the formation of stresses or cracks. With the new casting line, Taber increased monitoring and automation, and now has computer control of all critical casting and degassing parameters. Operators now interact with the system through an integrated SCADA control panel installed on the plant floor in order to monitor the correct mixture of several ingredients that make up the casting recipe. At the end of each cast, the system automatically generates a complete report of the heat number for reference and archival by quality control personnel. With this new system, Taber has not only achieved a greater level of quality control, but process transparency and product traceability.
  • Accuracy and Precision. An internally guided and double acting platen cylinder was installed, which has more loading capacity, guiding accuracy, and precision speed control (needed for hard alloys).
  • Consistency and Strength. The new casting line also includes a LARS® in-line degassing and purification system that refines and cleans the melt prior to casting. The LARS system mixes inert argon gas and a halogen gas into the molten aluminum through Almex’s patented in-situ gas preheating disperser system. This significantly reduces hydrogen and other impurities commonly found in liquid aluminum, including inclusions, nitrides, oxides, and alkali metals and also increases recovery through a minimal amount of dross creation. This high quality of the molten metal is, thus, dependably strong and consistent.
  • Environmentally Friendly. Taber rebuilt and integrated its water management system, which provides increased visibility of the water flow, temperature, quality, and maintenance. Water is discharged in a safe and controlled manner.

The micro-extrusion manufacturing lines have a production envelope with a circle size of 3 inches or less and a weight per foot of 1 lb. or less. Unlike traditional extrusion presses, these micro-extrusion presses are built in such a way to allow for the production of extrusions with wall thicknesses of 0.010 inches and tolerance capabilities of +/- 0.001 inches. This allows designers and engineers the freedom to engineer profiles that are impossible to extrude through conventional presses.

The addition of  ultra precision® extrusions allows the company to enhance its business to provide a wider range of profile sizes and competencies which blend beautifully with the various sectors already being served by Taber.

Friction Stir Welding Technology

In 2019, Taber  installed a new friction stir welding (FSW) line at its Russellville, Arkansas, manufacturing facility. Sometimes described as more of a forging process than actual welding – FSWis a solid-state joining technique used to join metals not easily fused with traditional welding. It is used in the aerospace, rail, automotive, marine, transportation, and other industries that use metals such as aluminum, copper and other metal alloys. The new FSW line that welds large, double-sided thick profiles, uses minimal cycles of the machine, which make it both efficient and precise. FSW also makes possible very high-quality welds with minimal distortion.

The addition of friction stir welding illustrates how Taber has proven itself to be dedicated to the technological advances in the industry, economic development, and job production. The line enables the company to be a vertically integrated supplier of FSW panels and assemblies in North America, with capabilities including aluminum extrusions, fabrication, billet casting, and micro-extrusions.

Already known for their wide range of capabilities, both broad and unique, the mayor of Russellville, Richard Harris, thanked Taber for choosing Russellville as their location, “The fact that you chose to expand and add new technology here is the highest compliment you can give the city and citizens where you live and work. Economic development and job creation is one of our top priorities. We congratulate Taber on this advancement.”

Joining Aluminum Extrusions Through Friction Stir Welding

2020-01-15T19:32:51+00:00January 15th, 2020|

What is Friction Stir Welding?

 

Friction stir welding is the method of joining two pieces of metal with no extra filler or material by subjecting the components to heavy plastic deformation, at elevated temperatures, that are still lower than the melting point. A rotating tool is thrusted between the components and, as friction heat is generated, the tool produces a severe plastic deformation under high pressure, at which time the weld interfaces are stirred together, and a homogenous structure is formed, creating a defect-free bond.

Why Friction Stir Welding?

FSW is a method of welding that is being used as an alternative method to fusion welding and other types of arc welding.

FSW vs. Fusion Welding  –  FSW offers three key benefits over fusion welding: metallurgical, environmental, and energy. The metallurgical benefits include: low distortion of workpiece (fine      microstructure, absence of cracking), good dimensional stability, and no loss of alloying elements. The environmental benefits include: no shielding gas required, no surface cleaning required, elimination of solvents required for degreasing, and consumable materials savings.  The energy benefits include: improved material use (joining different thickness), only 2.5% of energy needed for a laser weld, and decreased fuel consumption in light     weight, automotive, and ship applications. FSW is then, specifically because of its environmental and energy benefits, a more cost-effective method of welding. It is also a more economical choice due to low set up and training costs.

FSW vs. Other Types of Arc Welding  –  The joining of aluminum extrusions in friction stir welding is a process that can be easily automated, making it an ideal solution for industrial use in manufacturing services such as the marine, aerospace, automotive, transportation, and rail industries. FSW welds have effectively been used in the marine industries in the fish freezer panels of ships, on the deck panels of helicopter landing platforms on ships, and it has been used in various amphibious assault ships. In aerospace, FSW has been used for structures such as the fuselage, fins, and wings that require high-strength aluminum alloys. In the automotive industries, FSW is used for aluminum engine cradles and suspension struts, as well as rear seats and exhaust gas recirculation coolers. The railway industry has utilized FSW to make roof and floor panels, as well as heat sinks for cooling the high-power electronics of locomotives.

In military and defense, aluminum alloys are used as armor due to the combination of high ballistic performance and static strength that traditionally use MIG, gas metal arc, and tungsten arc welding. The reasons for the transition to FSW over the aforementioned arc welds are many — MIG welds cause stress corrosion at the weld toe, exfoliation occurring in the solution treatment, low ductility in butt welds, and liquidation due to the formation of low-melting point grain boundary. FSW welds are also more likely to pass the ballistic shock test.

Why FSW at Taber? New Aluminum Joining Techniques at Taber

 

In April of 2019, Taber Extrusions of Russellville, AR and Gulfport, MS announced the addition of Friction Stir Welding, “FSW,” capabilities to our existing portfolio which currently includes aluminum extrusions, fabrication, billet casting, and micro-extrusions. With the addition of in-house FSW capabilities, Taber is now a vertically integrated supplier of FSW panels and assemblies.

Taber’s engineering and manufacturing teams collaborated with Bond Technologies to create a custom Linear Seam machine. Taber’s new FSW machine is capable of welding large, double-sided thick profiles with minimal cycles of the machine; less cycles means greater efficiency and more precise results.

 

Taber offers quality custom extrusion design and advanced microextrusion capabilities and we are committed to providing our clients durable products that are both ecologically sound and cost effective. We chose FSW as a high-tech, alternative method to ensure a fast turn-around time, thereby reducing time to market.

The Benefits of Friction-Stir Welding in The Marine Industry

2020-01-15T19:31:37+00:00January 4th, 2020|

The communications relay of a submarine sticking out of the water, while the rest of the vessel remains submerged.

Over the last two decades, friction stir-welding has emerged and been established as an extremely effective alternative to traditional MIG welding for use in marine applications, particularly as the industry moves towards increased use of aluminum. The powerful combination of reduced weight from aluminum and increased strength of FSW welds can yield spectacular benefits for marine designs.

Aluminum can help you obtain weight and production savings and improve the quality and efficiency of your vessels and structures. Aluminum reduces weight without sacrificing structural strength. The unique qualities of extruded aluminum component design provides you with exceptionally high torsion strength resistance.

If you’re looking to cut costs of construction for your cruise ships, mega-yachts, defense vessels, passenger ferries, leisure craft, as well as offshore platforms and rigs, read on!

FSW is Well Suited For Marine Applications Because of The Nature of The Welds

The friction stir welding process is best utilized on long straight welds, as this allows for a more cost-effective and efficient process. Unsurprisingly, this happens to cover a significant portion of the flat structures that are used in the marine industry, such as floors, decks, bulkheads, and more parts that don’t require complex curves. Many of the structures that are welded in this process are alloyed aluminum extrusions.

Friction-stir welding is a great compliment to alloyed aluminum as it can successfully weld any of the normal range of aluminum alloys – whether that be the plate, extruded sections, forging, or castings – including high strength alloys such as 7xxx and 2xxx series aluminum. The ability to weld dissimilar materials effectively (for example, steel to aluminum) is an additional benefit of FSW.

An image showing the different potential marine applications of FSW, such as military vessels, cruise ships, and civilian transports.

Benefits of FSW For Marine Vessels

For projects both large and small, the FSW process stands to speed up the construction process and save money. The cost savings comes from the elimination of the required man-hours of traditional MIG welding, and also provides a stronger, higher quality weld, which cuts down on secondary repair costs down the line. Also, using complete components such as Modular FSW panels reduces the time and labor costs of measurement and cutting on the construction site.

Additional Benefits

  • Minimal distortion on the weld, and better aesthetics
  • More environmentally friendly (no UV radiation or fumes) as well more user-friendly
  • Removes flaws that are inherent to conditional welding methods – no porosity, no hot cracking, stronger fusion of the constituent elements
  • FSW is becoming more widely adopted and is less susceptible to errors due to the automated process

Infrastructure Applications of 6xxx Series Aluminum Alloys

2018-07-18T16:49:28+00:00July 17th, 2018|

It is estimated that 56,000+ bridges are structurally deficient in America with an estimated $123 billion in rehab needed. The solution? The 6xxx Series Aluminum Alloys. Not only can they be used for emergency repairs but they can provide a long-term solution to this infrastructure problem with minimal maintenance required.Let us review what sets this alloy apart, its advantages, and the types of projects the alloy is best suited for.

What is an aluminum alloy?  

Aluminum alloys are created by taking aluminum and adding elements, creating chemical compositions with enhanced properties. Once created, these compositions receive a 4-digit number with the first digit signifying a general series that characterizes its main alloying elements.

What does it mean when an alloy is a part of the 6xxx series

The main agents in the 6xxx series are silicon and magnesium in order to form magnesium silicide within the alloy. Alloy 6061 is the most commonly used of the series, typically used in truck and marine frames.

What are the advantages of the 6xxx aluminum alloys?

  • High Corrosion Resistance – 6xxx series aluminums can withstand abrasion, keeping their strength and durability in a variety of environments. This is one of the appeals to using it in infrastructure and architectural projects that hope to create structures with the intent of lasting decades. Whether its receiving harsh sunlight in the Nevada desert or nearly year round rain in Seattle, the alloy is able to hold up.
  • Extrudablitity – A unique feature of the 6xxx series is its extrudability. The ability to make specific, extruded parts from the alloy is another factor in why architectural and infrastructure members use this alloy. They typically require unusual, high-strength components and the power of extruded of 6xxx series is its ‘place-metal-where-you-need-it’ flexibility.
  • Heat treatable, weldable, flexible – 6061 is a highly weldable alloy, using tungsten insert gas welding or metal inert gas welding. After welding, the properties near the weld are those of 6061-O (a loss of strength of around 80%). However, MIG and TIG welded material can be heat treated again to bring the material back to the pre-welding temper. Another option may be Friction Stir Welding (FSW). With FSW, the profiles are joined together through the use of a specialized rotary machine tool. Although the material is heated and joined together through friction, the overall heat applied to the material is much lower and of shorter duration than MIG or TIG welding and the heat affected zone is much less and retains most of the original strength.

What are the applications of the 6xxx Series Aluminum Alloys?

It is this combination of advantages that make 6xxx Series Aluminum Alloys prime candidates for architectural and infrastructure projects. Such projects include:

  • Bridges or aluminum bridge decking: Extruded aluminums can be used to build traditional bridges or bridge decks can be pre-built in a modular fashion and moved to bridge sites. This method can limit the amount of time that bridges are under construction and save money in the long run.
  • Roof Structures: Typically implemented for arenas and gymnasiums, the 6063 or 6061 extruded tubes are used in large scale roofs with 5xxx alloy sheets covering them.
  • Pipelines: Because of their high corrosion resistance the 6xxx series is great for pipeline systems that have possibly acidic or dangerous materials flowing through them.
  • Automotive: Whether for a car, motorcycle, bus, or train, the 6xxx series is often used in the automotive industry for its high dent resistance and durability.

Taber Extrusions recognizes the hard work and precise engineering required for large-scale infrastructure projects. Capable of producing very large aluminum shapes with our exclusive 10” x 28” rectangular container along with our 16” and 20” round containers, we canconsistentlysupply our customers with some of the widest, most complex multi-void hollows in the industry.

Marine Applications of 5xxx Series Aluminum Alloys

2018-07-05T21:24:40+00:00July 5th, 2018|

The applications of the 5xxx series aluminum alloys range from shipping containers to their most prolific application, boats. Whether building a recreational boat, commercial ship, or naval vessel, the advantages that the 5xxx series of aluminum alloy have, make it the premier building material for anything marine related. Before we ‘dive’ into the specific advantages of the 5xxx series and it applications, lets break down what aluminum alloys are and what sets the 5xxx series apart.

What is an aluminum alloy and what does it mean when an alloy is considered part of the 5xxx series?

Simply, an aluminum alloy is created by adding elements to pure aluminum, creating a chemical composition that has enhanced properties (typically to increase strength). Once these compositions are created they are assigned a 4-digit number where the first digit signifies a general series that characterizes its main alloying elements. For the 5xxx series, its main agent is magnesium which gives the alloy high strength as well as good weld ability amongst other things.

What are the advantages of 5xxx aluminum alloys?

  • Weight Saving: By using 5xxx aluminum alloy, structures save an average of 55 to 67% of their weight. With comparable strength to mild steel, the alloy’s ability to decrease a structures weight can be hugely beneficial, especially for marine vessels. By saving weight the boats can increase payload, haul more equipment, and lower the amount of power required to power the boat.
  • Weld ability: With weld yield strengths of 100 to 200 MPa, the 5xxx series have good weld ductility without post weld heat treatments.
  • Corrosion resistance: The 5xxx series has lower resistance to corrosion making it ideal for any structure that will be coming in contact with water or chemicals. Through a 10-year seawater test, the tensile strength of the alloy showed reductions of only 2 to 5%.

What are the marine applications of 5xxx Series Aluminum Alloys?

  • Pleasure Boats: Made from both 5xxx and 6xxx series aluminum alloys, pleasure boats utilize the alloys ease of fabrication, corrosion resistance, and cost effectiveness for building their hull or other equipment.
  • Commercial ships: Many passenger vessels utilize the 5xxx series for both superstructures and equipment; ranging from 1000 to 2000 tons per ship. Since for many ocean liners appearance is important, the structures are painted but aluminum allows for a 50% longer time frame till repainting.
  • Naval Vessels: Each year, 6000 tons of aluminum is used on destroyers. Within the past decade, 5456 plate and extrusions have become the standard for the welded deckhouse structures of destroyers. The weight saving ability of the 5xxx series allows the ship to maintain stability with its narrow hull that is needed to reach high speeds. Beyond the main structure, the alloy can also be employed for a variety of equipment including doors, windows, gratings, lockers, bunks, etc.

It is the use of the aluminum alloys that has allowed the marine industry to undergo a technological revolution. While the aluminum may have an initial cost premium, its ability to create lighter ships with lower maintenance costs means that the ship will be a worthwhile investment over the course of its life. And though boats may not be the first thing you think of when discussing the application of an aluminum alloy, the 5xxx series aluminum alloy has transformed the marine industry for the better.
