Aluminum Alloy, Hand Forgings 7.7zn 2.4mg 1.6cu 0.16cr (7049-T7352) Solution Heat Treated, Stress Relieved By Compression, and Precipitation Heat Treated(Cancelled Mar 2003) MAM4247B

This specification covers an aluminum alloy in the form of hand forgings procured to metric dimensions. AMS 4247 is the inch/pound version of this MAM.

These forgings have been used typically for parts requiring a combination of high strength and resistance to stress-corrosion cracking and for parts requiring stability during machining, but usage is not limited to such applications.
