Mingtai Aluminum brings you to explore 7075 aluminum

2017-08-22

Aluminum plate is one of the important products in the field of aluminum processing. According to the alloy grades can be divided into eight alloy washed, of which. 7000 series alloy is Al-Zn-Mg alloy, is a heat treatment alloy, belonging to the aviation series, which is the aluminum plate in the more high-end areas. To 7000 series on behalf of the product 7075, mainly containing zinc. Also belong to the aviation series, is aluminum and magnesium zinc copper alloy, heat treatment, are super-hard aluminum alloy, a good wear resistance.

7000 series alloy is usually used as welding material, or used as aircraft materials, to super-hard aluminum alloy 7075 alloy as the representative. 7075 aluminum used in the manufacture of aircraft structures and other requirements of high strength, high corrosion resistance of high-stress structural parts, such as aircraft, the lower wing wall panels, frame and so on. After the solution treatment is good plasticity, heat treatment strengthening effect is particularly good, in the 150 degrees below the high strength, and has a particularly good low temperature strength, poor welding performance, stress cracking tendency.

7075 aluminum alloy

In recent years, sportswear such as ski poles, golf clubs and the like have also been made using this alloy. 7075 alloy aluminum heat treatment, multi-purpose T651, this treatment can make T6 after treatment of the residual stress, by stretching and homogenization, to prevent the work piece when the distortion caused by distortion. T73 treatment, will reduce the mechanical properties, but there is the effect of reducing the stress corrosion tendency.
