About Aluminum

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.

Cold-rolled sheets are cut from large pieces to the widths and lengths listed, so the edges may not be parallel.

Cold-drawn bars are formed by a die for close-tolerance widths, then cut to the lengths listed.

All come with a traceable lot number and test report. While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.

Also known as flat stock, these sheets and bars are precision ground on the top and bottom. The sides have a cut or milled edge. While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.
