Alloy Description

Aluminum alloy 7050 is an aerospace grade of aluminum combining high strength, stress corrosion cracking resistance and toughness. It is particularly suited for heavy plate applications (3" to 6" thick) due to it's lower quench sensitivity and retention of strength in thicker sections. Aluminum 7050 therefore is the premium choice aerospace aluminum for applications such as fuselage frames, bulkheads and wing skins.

Aluminum 7050 plate is available in two tempers. T7651 (AMS 4201) combines the highest strength with good exfoliation corrosion resistance and average SCC resistance. T7451 (AMS 4050) provides better SCC resistance and excellent exfoliation resistance at slightly lower strength levels. 

Aircraft Materials can also supply 7050 in round bar with temper T74511 (AMS 4342).
