7020 aluminum alloy is a medium-high strength Al-Zn-Mg alloy with high strength, good welding performance and process performance. It is the main welding structural material for aerospace vehicles and ground vehicles and equipment, and is widely used in the manufacture of high-speed trains. Bodywork. 7020 aluminum alloy has good comprehensive properties after heat treatment. The strength of 7020 aluminum alloy is greater than 6082, but its forming ability also deteriorates accordingly.
