The values shown in the mechanical properties table apply to a test sample prepared by forging representing extruded forging stock and forgings made from cast billets,hot rolled plate and extruded stock. The specification contains other properties for test samples prepared by machining representing extruded foring stock and forgings made from extruded stock. THe hardness values apply to forgings and forged test pieces.

Applications:
High strength structural components: aircraft (e.g. fittings and wheels), military vehicles and bridges, forgings for trucks and machinery (hydraulic etc.). Weapons manufacture, structural applications.

Characteristics:
Heat treatable alloy. High mechanical strength slightly higher than 2011 and 2017A.
