Aluminium alloy 2014A is a high-strength copper alloy containing approximately 4–5% copper, supplied in extruded bar, tube, and profile forms in the fully heat-treated condition (solution heat treated and artificially aged). The alloy is normally stocked in the T6511 condition, where it is stress relieved by controlled stretching with minor straightening after ageing. Exceptions apply for sizes below 10 mm diameter and above 203.2 mm diameter, which are supplied in the T6 condition only. Sizes over 203 mm diameter are manufactured to chemical composition only. Aluminium alloy 2014A offers very good machinability and is widely used for high-strength structural components, particularly in the aerospace and defence industries.
