7050 aluminum T7751 is a high-strength Al-Zn-Mg-Cu alloy in an overaged temper condition that provides excellent stress-corrosion cracking (SCC) resistance and fracture toughness at the expense of some peak strength compared to T7351. T7751 is specified for critical aerospace structure, particularly thick-section forgings and extrusions where sustained tensile stresses and corrosive environments necessitate resistance to SCC initiation and propagation.
