  • Publication number: 20150299836
    Abstract: A method of manufacturing a formed component for aircraft use according to the present invention includes: subjecting a material made of an aluminum alloy to solution heat treatment; then forming the material into a predetermined shape under cold working conditions; and thereafter subjecting the material to artificial age-hardening treatment. Under the cold working, the material is formed into the predetermined shape while a strain corresponding to a temper T8 is being imparted to the material by a roll forming apparatus. This makes it possible to manufacture a formed component for aircraft use made of an aluminum alloy in a T8 state at a lower cost than conventional art.
