7075 aluminum is a high-strength Al-Zn-Mg-Cu alloy used primarily in aerospace structures, offering yield strengths of 70–80 ksi in peak-hardness T6 condition with moderate corrosion resistance improved in overaged T73 and T7351 variants at reduced strength levels. The extensive temper range (T6 through T7751) provides design flexibility from maximum strength applications to enhanced stress-corrosion cracking resistance in critical components, with elastic properties (Young's modulus ~10.4 Msi, density 0.101 lb/in³) consistent across temper variants.
