7175 aluminum T6151 is a high-strength Al-Zn-Mg-Cu alloy in a solution heat-treated, stress-relieved, and overaged temper used primarily in aircraft structural applications demanding exceptional fatigue resistance and stress-corrosion cracking (SCC) resistance. The T6151 condition provides yield strengths of 435–505 MPa with improved toughness and corrosion performance compared to T6, making it suitable for critical fuselage and wing components operating under sustained or fluctuating loads.
