7049/7149 Aluminum T6151 is a high-strength Al-Zn-Mg-Cu aerospace alloy in a overaged temper condition that provides improved stress-corrosion cracking (SCC) resistance and fracture toughness compared to T6, with typical yield strengths of 65–75 ksi and applications in highly stressed structural components, fuselage skins, and wing elements where damage tolerance is critical.
