Product Code:SAE AMS4141
Title:Aluminum Alloy Die Forgings, 5.6Zn - 2.5Mg - 1.6Cu - 0.23Cr (7075-T73), Solution and Precipitation Heat Treated
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:This specification covers an aluminum alloy in the form of die forgings and forging stock ordered to inch/pound units. These forgings have been used typically for parts requiring good resistance to stress-corrosion cracking but with lower strength than AMS4126, but usage is not limited to such applications.
