Abstract

Aluminum alloy 7449 in the T7651 temper is solution heat treated, stress relieved, and overaged. This processing produces an alloy of high strength, good corrosion/exfoliation resistance, and good toughness. An application of interest is the upper-wing skin of aircraft structures. This datasheet provides information on composition and tensile properties as well as fracture toughness. It also includes information on forming. Filing Code: AL-402.
