7075 Aluminum T73
Verifiedmetal· T7351
7075 aluminum alloy in T73 temper is a high-strength aluminum-zinc-magnesium-copper alloy overaged to improve stress-corrosion cracking resistance while maintaining excellent strength characteristics; it is widely used in aircraft structures, fuselage skins, and aerospace components requiring superior fatigue and corrosion resistance in the 40,000–70,000 psi yield strength range.
