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 fuselage bare sheets. The alloy posesses, in several tempers, a superior combination of weldability, strength, and corrosion resistance. This datasheet provides information on composition, physical properties, microstructure, tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: AL-430. Producer or source: Alcan Inc. and Alcan Aerospace.
