Commercial Alloy

2014A T651 Sheet and Plate

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.
Machinability of aluminium alloy 2014A is very good.
Typical applications of aluminium alloy 2014A are high strength componenets especially for use in the aerospace and defence industries.
