AA 6351 wrought alloy contains silicon and magnesium in such amounts that Mg2Si is present as the precipitation hardening constituent with proper heat treatment. The 6000 series alloys are less strong than most of the 2000 and 7000 series aluminum alloys. The formability and corrosion resistance of AA 6351 are good. This datasheet provides information on composition, physical properties, hardness, tensile properties, and shear strength as well as fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Al-319. Producer or source: Various aluminum companies.
