7020 aluminum tubing

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, ground vehicles and equipment. It is widely used in the manufacture of high-speed train body. 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.

7020 aluminum tubing

7020 aluminum tubing, with high strength, good welding performance and process performance, is the main welding structural material for aerospace, ground vehicles and equipment.

7020 aluminum tubing is used as an ideal lightweight material in the pantograph of rail vehicles because of its excellent properties such as light weight, high strength, good thermal conductivity, easy formability and good welding performance. As the power receiving device of rail transit vehicles, pantograph undertakes the interface between catenary and on-board electrical equipment. The pantograph on high-speed rail is generally welded with 7020 T6 aluminum alloy round pipe. Our company can directly make 7020 aluminum tubing to avoid welding cracking, which is widely used on high-speed rail trains in China.
