To the 7075 aluminum alloy, in addition to the use of daily life, with the continuous improvement of technology, aluminum 7075 is also began to use in important transportation areas, such as aerospace structure materials, at the present, it has entered the development of the automotive field. With the rapid development of modern aerospace industry, higher requirements for the comprehensive properties of high-strength aluminum alloys are put forward. At the same time, the development of modern nuclear industry and transportation industry is in urgent need of high performance, light and economic structure materials, aluminum alloy technology has become the trend of the times.

The 7000 series aluminum is the strongest material in aluminum alloy. Especially, 7075 is super hard aluminum this is the main advantages of 7075 aluminum. With 7075-T651 aluminum alloy especially high quality, 7075 aluminum is praised as the best product of aluminum alloy, which has high strength and far better than any soft steel. The 7075 aluminium alloy has good mechanical and anodic reaction. The common product of 7075 aluminum alloy are 7075 aluminum sheet and 7075 aluminum profile. The representative applications are aeronautics and astronautics, mold processing, mechanical equipment and fixture, especially for the manufacture of aircraft structures and other high stress structures requiring high strength and corrosion resistance.
