English name  ：Aluminum Alloy Forgings 5.6Zn - 2.5Mg - 1.6Cu - 0.23Cr (7175-T7452) Solution Heat Treated, Stress Relieved, and Precipitation Heat Treated

标准简介：
This specification covers an aluminum alloy in the form of die forgings, hand forgings, and forging stock.

These products have been used typically for parts requiring a high level of mechanical properties and good resistance to stress-corrosion cracking, but usage is not limited to such applications
