Temper Selection Guide

O Temper

Softest condition, maximum ductility. Best for cold forming, bending, and deep drawing operations where the material must be shaped before heat treatment.

T4 Temper

Solution heat-treated and naturally aged. Offers a balance of formability and moderate strength. Suitable for parts that require bending after heat treatment.

T6 Temper

Full artificial aging yields maximum strength. The go-to choice for structural components, machine parts, and applications demanding highest mechanical performance.

T651 Temper

T6 with stress-relief by controlled stretching. Minimizes distortion during machining. Recommended for tight-tolerance CNC parts that must remain dimensionally stable.
