Aluminium 2014A
Aluminium 2014A T651 Sheet and Plate
a very robust 4–5% copper alloy that is completely heat-treated (solution heat-treated & artificially aged) and manufactured as extruded bars and profiles. With the exception of diameters under 10 mm in diameter and more than 203.2 mm in diameter, are typically stored in the T651 state (stress eased through controlled stretching). exclusively for T6. A diameter of more than 203 mm is produced only according to chemical composition. 2014A aluminium alloy has excellent machinability.
Strong parts, particularly for use in the aerospace and military sectors, are typical uses for aluminium 2014A alloy.
