Aluminum’s versatility and prevalence have made it a staple in various industries globally. Its numerous benefits position it as a favored material choice. Join us as we delve into hard alloy aluminum extrusion manufacturing — a cutting-edge method that enhances aluminum’s mechanical properties and expands its range of applications.

Recognizing aluminum

Despite being plentiful in the Earth’s crust, aluminum is rarely found in its pure form. Various forms of aluminum and its alloys are esteemed for their high strength-to-weight ratio, low density, corrosion resistance, and durability. Aluminum’s low density makes it an ideal lightweight alternative to steel, being 2.5 times less dense and favorable for applications needing portability.

Many aluminum alloys are malleable and ductile, making them effortless to machine and form. They possess excellent electrical and thermal conductivity while lacking magnetic and sparking properties. Recycling aluminum is possible due to its low re-melting temperature, which requires only 5% of the energy used in primary metal production. It also maintains its properties after multiple recycling cycles, up to 75%, highlighting its sustainability. 

What are aluminum grades?

Aluminum alloys are created by blending pure aluminum with various alloying elements to modify their mechanical properties, corrosion resistance, formability, and machinability. The Aluminum Association classifies and maintains the different grades of aluminum based on their composition and how they respond to mechanical and thermal treatment.

Wrought and cast are the two categories of aluminum alloys. Mechanical processes are employed like forging, bending, and rolling to shape wrought aluminum alloys. In contrast, cast aluminum alloys are formed by melting and pouring into molds to create specific shapes. Both types of aluminum alloys have their unique properties and applications. Wrought aluminum is worked in solid form, while cast aluminum is melted and poured into a mold.

Let’s dive deeper into wrought aluminum!

Wrought aluminum  possesses remarkable strength, and people can mold it into various shapes. The grade’s composition is achieved by melting aluminum ingots with a measured quantity of alloying metal. Rolling, forging, or extruding transforms the melted aluminum alloy into billets or slabs. Heat treatment is applied further to enhance the natural properties of the aluminum alloy.

Each wrought aluminum grade is assigned a unique four-digit number code:

  • To modify pure aluminum, you add the primary alloying element, represented by the first digit. The primary alloying element impacts the grade’s properties in a sequence.
  • The second digit denotes the alloy modification and requires specific documentation using IADS. If the number assigned is zero, the alloy is either unmodified or in its original state.
  • The third and fourth digits are random numbers in the sequence assigned to a specific alloy. For the 1000 series, these digits represent the alloy’s purity.

We can divide aluminum grades into several categories. The purest form of aluminum with the lowest yield and tensile strength belongs to the 1000 series. On the other hand, the 7000 series comprises alloys of magnesium, zinc, and copper and has the highest tensile and yield strength.

1000 Series

Aluminum is a metal that can be very pure, with a grade of 99% or higher. There are different types of aluminum alloys, and one of them is called the 1xxx series. These alloys are good at resisting damage from rust and can carry heat and electricity well. Electric transformers and power grids often utilize them.

3000 Series

3xxx series aluminum alloys are a type of metal often used for various purposes because they have a good balance of strength and flexibility. Manufacturers add manganese to create these alloys, granting them unique properties.

6000 Series

The 6xxx series of aluminum alloys is a versatile and robust material with many construction and architectural uses. They can be heated and welded to fit different shapes and designs and are known for their ability to resist rust and wear over time. Perfect for many construction and architectural designs.

Hard Alloys

2000 Series

The material becomes very strong and tough when copper is mixed with aluminum to create 2xxx series aluminum alloys. Another exciting thing about this alloy is its strength can increase even more by applying heat treatment.

5000 Series

The 5xxx series is a type of material that is made stronger by adding magnesium to it. It can be welded easily and is resistant to rusting, especially in places with a lot of saltwater, like the ocean. People often use it to construct boats, shipping containers, and other structures exposed to salty and wet environments.

7000 Series

Various sectors, such as aerospace, utilize aluminum alloys for their operations. One type of alloy, the 7xxx series, is solid and can withstand harsh weather conditions. This alloy adds elements like zinc, magnesium, copper, and chromium.
