7075 aluminum T61511 is a high-strength Al-Zn-Mg-Cu alloy in a stress-relieved condition achieved through controlled stretching and artificial aging, designed for critical aerospace structures requiring maximum strength-to-weight ratio and fatigue resistance. This temper provides tensile strengths in the 70–80 ksi range with improved stress-corrosion cracking (SCC) resistance compared to T6, making it suitable for fuselage skin, wing components, and highly stressed fasteners in military and commercial aircraft.
