Aluminium, Commercial Alloy

2014A T651 Sheet & Plate

A high strength aluminium alloy which retains its strength after heat treatment.

A high strength 4 to 5% copper alloy produced in extruded bar and profile form, in the fully heat treated condition (solution heat-treated & artificially aged).

Normally stocked in the T651 condition (stress relieved by controlled stretching) except for sizes under 10mm diameter and over 203.2mm diameter (T6 only). Over 203.mm diameter is manufactured to chemical composition only.
