Research status of 7075 aluminum alloys
Chen Furong, Li Guowei
Abstract:
7075 aluminum alloy, characterized by high strength and good toughness, is a light weight and high strength structural material with a good application prospect. Upon consulting a large number of literatures and combining with the work carried out by the research group in recent years, the authors introduced the development and application of 7075 aluminum alloy at home and abroad, and also introduced the three main aging treatment processes and two ways of precipitation of the alloy. The welding process of 7075 aluminum alloy is mainly discussed. Aiming at the existing problems of 7075 aluminum alloy, the direction of research and development in the future is put forward.
