Frequently Asked Questions

What is the difference between T5 and T51 heat treatment?

T5 designates an artificial aging treatment applied after a high-temperature forming process such as casting or extrusion, improving hardness and strength without a full solution heat treat. T51 is a stress-relieved variant of the T5 temper, achieved by controlled stretching after forming to reduce residual internal stresses—commonly required for precision aerospace and defense components where dimensional stability is critical.
