Aircraft design, selection of structural materials should have high specific strength and stiffness, to reduce the structural weight of the aircraft, to improve the flight performance or increase economic benefits, but also should have the good processability, facilitates to produce the required parts. Say simply, because the aluminum alloy light weight, high strength, convenient processing, the price is relatively cheap, so all kinds of aircraft aluminum alloy as the main structure material. On the aircraft skin, beam, ribs and stringers, bulkheads and gear can be made of aluminum alloy.
