High-strength aluminum alloy 7075 material (Al-Zn-Mg-Cu)

- May 09, 2018-

7000 series alloy is used for aircraft materials and is represented by super hard aluminum alloy 7075 alloy. In recent years, sporting goods such as ski poles and golf clubs have also been made using this alloy. 7075 alloy heat treatment, more use T651, this treatment can make the residual stress after T6 treatment, after stretching and uniform, in order to prevent the processing of the workpiece when the distortion occurs. T73 treatment will reduce the mechanical properties, but it has the effect of reducing stress corrosion.
