Alloy 7050 Aluminum 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 thickness range. Because it is less quench sensitive than most aerospace aluminum alloys, 7050 retains its strength properties in thicker sections while maintaining good SCC resistance and fracture toughness levels. Alloy 7050 Aluminum plate is available in two tempers: T7651 combines the highest strength with good exfoliation corrosion resistance and average SCC resistance; and T7451 provides better SCC resistance and excellent exfoliation resistance at slightly lower strength levels. Alloy 7050 sheet is available bare and in the T76 temper.

Applications
7075 applications include fuselage frames and bulkheads where section thicknesses are 2 to 6 inches. Typical sheet applications include wing skins. The major usage is in plate applications requiring thicknesses over 2 inches where 7050 has superior properties.
