7005 aluminum plate Extruded materials are used to manufacture welded structures with both high strength and high fracture toughness, such as trusses, rods and containers of transportation vehicles; Large heat exchanger and parts that cannot be solid melt treated after welding; It can also be used to manufacture sports equipment such as tennis rackets and softball bats.

Aluminum (Al) is a light metal, and its compounds are widely distributed in nature. The resources of aluminum in the crust are about 40~50 billion tons, ranking third only after oxygen and silicon. It is the first major metal category among metal varieties. Aluminum has special chemical and physical properties. It is not only light in weight and hard in texture, but also has good ductility, conductivity, thermal conductivity, heat resistance and nuclear radiation resistance. It is an important basic raw material for national economic development.
