7050 aluminum is a high-strength Al-Zn-Mg-Cu alloy used in aerospace structures and airframes where exceptional damage tolerance and fracture toughness are required. The T7452 temper provides stress-relief through controlled heat treatment to minimize residual stresses from forging while maintaining high static strength (yield and ultimate tensile strengths in the 435–480 MPa range) and improved resistance to stress-corrosion cracking compared to peak-aged tempers.
