  • HIGH STRENGTH, HIGH STRESS CORROSION CRACKING RESISTANT AND CASTABLE AL-ZN-MG-CU-ZR ALLOY FOR SHAPE CAST PRODUCTS
    Publication number: 20150247229
    Abstract: The present invention provides an Al—Zn—Mg—Cu casting alloy that provides high strength for automotive and aerospace applications and optimized stress corrosion cracking resistance in highly corrosive and tensile environments. The inventive alloy composition includes about 3.5 wt. % to about 5.5 wt. % Zn; about 1.0 wt. % to about 3.0 wt. % Mg; about 0.5 wt. % to about 1.2 wt. % Cu; less than about 1.0 wt. % Si; less than about 0.30 wt. % Mn; less than about 0.30 wt. % Fe; and a balance of Al and incidental impurities.
