Application:In modern aircraft structural parts, the use of 1500-2000 kinds of aluminum castings, 7075 aluminum plate is widely used in products with high strength requirements.according to the different conditions and parts of the aircraft, the main use of three basic types of aluminum alloy: the high-strength aluminum alloy, heat-resistant aluminum alloy, corrosion-resistant aluminum alloy. High-strength aluminum alloy is mainly used for aircraft fuselage parts, engine compartment, seats, operating systems, in most cases can replace aluminum die forgings. High-strength aluminum alloy in Russia is mainly aluminum - copper alloy, the main use of aluminum in the United States - copper - fierce line.
