Description
AA 7150 is a high-strength aluminum-zinc-magnesium-copper alloy (~6.2–6.9% Zn, 2.0–2.7% Mg, 1.9–2.5% Cu) with zirconium, developed as an improved version of 7050 with higher strength in T6 temper while maintaining good toughness for thick plate. It is used in T651 or T7751 temper depending on the corrosion resistance requirements. Applications include upper wing skins, stiffeners, and structural plate in commercial transport aircraft.
