The extrusion process makes the most of aluminum’s unique combination of physical characteristics. Its malleability allows it to be easily machined and cast, and yet aluminum is one third the density and stiffness of steel so the resulting products offer strength and stability, particularly when alloyed with other metals. Additional complexities may be applied during this process to further customize the extruded parts. For example, to create hollow sections, pins or piercing mandrels are placed inside the die. After the extrusion process, a variety of options are available to adjust the color, texture and brightness of the aluminum’s finish. This may include aluminum anodizing or painting.
Today, aluminum extrusion is used for a wide range of purposes, including components of the International Space Station. These diverse applications are possible due to the advantageous attributes of aluminum, from its particular blend of strength and ductility to its conductivity, its non-magnetic properties and its ability to be recycled repeatedly without loss of integrity. All of these capabilities make aluminum extrusion a viable and adaptable solution for a growing number of manufacturing needs.
