I need material properties of Al alloy 771-T71
- Thread starter nstolten
- Start date
From ASM Metals Reference book:
771.0-T71 Sand cast Solution treat at 590C cool in still air. Age at 140C for 15hrs.
Composition
0.9%Mg 7.0%Zn 0.13%Cr 0.15%Ti Remain: Al
Properties: (for -T6 heat treat. Separately cast bars.)
Tensile: 345MPa Yield: 275MPa Elongation: 9%
I would expect that -T71 would have lower properties overall since its an overaged (stabilized) heat treat condition.
Also you should expect properties to vary significantly depending on location and section size of the casting.

The properties are readily available at MatWeb.
