Choudhary Metal Distributor stock 7050 ALUMINIUM PLATES, which is available in two
tempers: T7451 (formerly T73651) offers better stress corrosion cracking resistance and
excellent exfoliation resistance at slightly lower strength levels; and T7651 combines the
highest strength with good exfoliation corrosion resistance and average stress corrosion
cracking resistance.Alloy 7050 aluminum plates are the principal choice for aerospace
applications, especially in the 3-6 inch thickness range. It exhibits better toughness/corrosion
resistance characteristics than the older, more established alloy 7075. Since it is less quench
sensitive than most other aerospace alloys, this alloy maintains its strength properties in
thicker sections while retaining good stress corrosion cracking resistance and fracture
toughness levels. AMS 4050 is commonly associated with 7050, though various manufacturers
require their own specifications.
