7085 T7652 Aircraft Aerospace Aviation Aluminum Alloy Forgings for Wing Beam
A kind of high strength and high hardenability forging aluminum alloy has been developed since 1990s. 7085aluminum alloy plate forgings can solve the contradiction between specification hardenability, performance and residual internal stress, and have excellent comprehensive properties, especially in fracture toughness, without the influence of thickness.
