The 7022 aluminum bar is a premium high-strength 7000-series aluminum alloy bar designed for demanding structural and precision machining applications. It contains zinc as the primary alloying element along with magnesium and copper, delivering exceptional mechanical strength, corrosion resistance, and dimensional stability compared to many other aluminum alloys.
7022 Aluminum Bar
The 7022 aluminum bar is a premium high-strength 7000-series aluminum alloy bar designed for demanding structural and precision machining applications. It contains zinc as the primary alloying element along with magnesium and copper, delivering exceptional mechanical strength, corrosion resistance, and dimensional stability compared to many other aluminum alloys.
The alloy demonstrates excellent machinability and resistance to stress corrosion cracking, making it widely used in mold making, aerospace components, automotive structural parts, defense equipment, and other high-load industrial uses. Available in multiple bar shapes — including round, square, flat, and hex bars — and various tempers such as T6 and T651, this product can be custom-sized for thickness, width, and length to meet specific engineering specifications.
