NORAL C77S is a high strength, heat treatable, wrought aluminum alloy that is recommended for highly stressed components. It responds to the precipitation hardening heat treatment, producing tensile strengths in excess of all other aluminum alloys. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive, shear, and bearing strength as well as fracture toughness and fatigue. It also includes information on as well as forming, heat treating, machining, and joining. Filing Code: Al-10. Producer or source: Northern Aluminium Company Ltd.
