Alloy 7055 extruded products in the T74511 and T76511 tempers have a combination of high strength, excellent corrosion resistance, toughness, fatigue, and formability. The alloy was developed as an advance over aluminum alloys 7178 and 7075. This datasheet provides information on composition, tensile properties, and compressive strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming. Filing Code: AL-397. Producer or source: AEAP-Alcoa Engineered Aerospace Products.
