Abstract

ALCOA 7475 was developed for sheet and plate applications that require high strength and a high level of guaranteed fracture toughness. It has the highest toughness for a given strength of the commercially available high-strength aircraft alloys. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and shear andbearing strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming, heat treating, and surface treatment. Filing Code: Al-232. Producer or source: Aluminum Company of America. Originally published as Aluminum 7475, June 1978, revised November 1989.
