7005 aluminum alloy profile for transit vehicles

In order to accelerate the development of China's transportation tools towards modernization, high-speed and lightweight, the state has listed the localization and industrialization of large aluminum alloy profiles for vehicles as a key scientific and technological research project. 7005 aluminum alloy belongs to Al Zn mg Cu system, which can be strengthened by heat treatment. It not only has good mechanical properties, corrosion resistance, thermal stability and welding properties, but also has good extrusion properties and on-line quenching properties. 7005 aluminum alloy profile for transit vehicles has gradually become one of the main materials of large aluminum alloy profiles for vehicles. Adding an appropriate amount of trace elements such as Mn, Cr and Zr to Al Zn mg Cu alloy can effectively improve the recrystallization temperature and weldability of the alloy, which is widely used in structural parts requiring load-bearing and weight reduction.
