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 is an extremely rich metal element on the earth, and its reserves rank the first among metals. At the end of the 19th century, aluminum came to the fore and became a competitive metal in engineering applications. The development of the three important industries of aviation, construction and automobile requires that the materials have unique properties of aluminum and its alloys, which is greatly conducive to the production and application of this new metal aluminum.
