Aluminium, Commercial Alloy
2014 T6511 Bar & Extrusion
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 T6511 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.
