Alcan 6056 alloy is an Al-Si-Mg-Zn-Cu-Mn weldable alloy, developed to provide medium strength similar to the incumbent 2024 alloy, with a lower density. This datasheet covers ALCAN 6056 in several tempers as thin extrusions. The alloy possesses, in several tempers, a superior combination of weldability, high-strength, and corrosion resistance. This datasheet provides information on composition and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as forming and heat treating. Filing Code: AL-419. Producer or source: Alcan Inc.
