Alcoa 7050-T7451

Generic Family: Aluminum - Wrought - Al-Zn AlloySupplied by: Alcoa North American Rolled Products
Alloy 7050 is the premier choice for aerospace applications requiring the best combination of strength, stress corrosion cracking (SCC) resistance and toughness. It is particularly suited for plate applications in the 3 to 6 inch (76.20 to 152.40mm) thickness range. Alloy 7050 exhibits better toughness/corrosion resistance characteristics than alloy 7075. Because it is less quench sensitive than most aerospace aluminum alloys, 7050 retains its strength properties in thicker sections while maintaining good stress corrosion cracking resistance and fracture toughness levels.

Alloy 7050 plate is available in two tempers: T7651 combines the highest strength with good exfoliation corrosion resistance and average SCC resistance; and T7451 (formerly T73651) provides better SCC resistance and excellent exfoliation resistance at slightly lower strength levels.

Alloy 7050 sheet is available bare and Alclad in the T76 temper. Alcoa developed alloy 7050 and has been the major supplier of this alloy since the early 1970's.
