6082 belongs to the 6××× series (Al-Mg-Si) alloy aluminum plate, is able to heat treatment can strengthen the aluminum alloy plate, has moderate strength and good welding performance, corrosion resistance, mainly used in transportation and structural engineering industry. Such as Bridges, cranes, roof frames, transport aircraft, transport ships and so on. In recent years, with the rapid development of shipbuilding industry at home and abroad, reducing hull weight, improving ship speed, seeking to replace steel parts of aluminum alloy material, has become an important issue facing aluminum processing industry and shipbuilding industry. With moderate strength, good corrosion resistance and light weight, 6082 aluminum alloy is the ideal material for the manufacture of high-speed ship components.
