On the right, are a bunch of aluminum pieces that are unevenly, yet elegantly stacked vertically, showcasing different shaped profiles on a clear white background.

Aluminum extrusions offer many advantages when material comparisons are considered. Aluminum extrusions have revolutionized the way our world is built today, offering the ability to create complex shapes with precision and outperforming alternative materials such as wood, plastic, steel, and other metals. Construction, transportation, military, aerospace, and consumer goods are just a few of the applications for which engineers and designers now turn to aluminum extrusions as the standard.

 

When designing aluminum extrusions, you must take into consideration aluminum alloys and the specific application requirements, including load-bearing capacity, structural integrity, and functionality. Selecting the right alloy and surface treatment becomes vital — considering the intended environment, such as temperature variations and exposure to corrosive elements. Designers must also optimize shape and geometry — minimizing material waste and ensuring easy fabrication or assembly after the extrusion process.

 

Addressing these factors early on unlocks the full potential of aluminum extrusions, creating visually appealing, highly functional, cost-effective sustainable products. As Steve Jobs once said, “Design is not just what it looks like and feels like. Design is how it works!”

 

Tooling Cost and Lead Time

Tooling costs and lead times are critical factors in the aluminum extrusion process and other manufacturing methods. Tooling refers to the creation of molds, dies, and other specialized equipment required for a manufacturing process, while lead time refers to the time required for tooling preparation, production setup, and the completion of a production run. Properly considering these factors is crucial for achieving efficient production, controlling costs, and meeting project timelines.

 

Aluminum alloys offer distinct advantages here, simplifying the fabrication of tooling components due to their unique properties: easier machinability, lower melting point, reduced wear on tools, superior thermal conductivity, lighter weight, corrosion resistance, abundant availability, and overall efficiency in manufacturing processes. Steel, on the other hand, demands more complex and time-consuming tooling processes due to its melting point and more intricate machining requirements.

Extrusion: A Brief Comparison Between Materials

 

Extrusions revolutionized manufacturing, enabling precise, complex shape creation, heightened efficiency, and versatility across materials like plastics, wood, and metals such as aluminum, steel, and copper. With a wide range of materials available, form and function must go hand in hand, and a great designer, engineer, or builder understands the value of knowing and choosing the right tools and materials for a successful build. Here are brief material comparisons.

 

Among these materials, aluminum, and aluminum alloys offer several advantages over alternative materials. Its properties provide a compelling combination of strength-to-weight ratio, corrosion resistance, formability, electrical and thermal conductivity, sustainability, and energy efficiency. When compared to roll-formed steel, aluminum extrusion provides similar strength with significantly reduced weight, making it a preferred choice for applications that require structural integrity while prioritizing weight reduction.

 

Copper extrusions, although strong —are much denser than aluminum, resulting in lower strength-to-weight ratios. Molded plastic materials, while lightweight, generally have lower strength and thermal conductivity compared to aluminum.

 

Although it is a natural and versatile material, wood is not as strong or lightweight as aluminum. Vinyl extrusions, on the other hand, are resistant to corrosion —but lack the strength and thermal conductivity of aluminum.

 

With the necessity of sustainable products, aluminum is the perfect choice. Known as the “Green Metal,” aluminum is one of the most environmentally friendly metals and can be recycled infinitely.

 

Overall, aluminum extrusion offers a more compelling set of properties that make it the preferred choice for various applications when compared to alternative materials utilized in the extrusion process.
