Abstract

Alcan 7449 is an Al-Mg-Zn-Cu-Zr alloy, developed to provide higher-strength properties than incumbent 7175 and 7150 alloys. This data sheet covers the Alcan alloy 7449 in the forms of thick extrusions and extruded bars. Tempers are presented that show improvement over both 7150 and 7175 aluminum alloys. This datasheet provides information on composition, physical properties, elasticity, and tensile properties and bearing strength as well as fatigue. It also includes information on corrosion resistance as well as forming and heat treating. Filing Code: AL-403. Producer or source: Alcan Inc.
