IncoMAP alloy A1-905XL is a low density aluminum alloy designed to replace alloy 7075-T73 in forgings where weight is critical. Its density is 8% less than that of alloy 7075-T73. Heat treatment is not required to develop its strength. This datasheet provides information on composition, physical properties, microstructure, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Al-295. Producer or source: Inco Alloys International Inc..
