Mill hardened to provide properties not available by standard age hardening.

Alloys 3 and 10 only.

The mechanical properties of BeCu alloys are a combination of composition, cold work and age hardening.

The relationship of temper designations from different vendors, users and standards is shown in the table above.

More information about BeCu alloys is available from manufacturers such as BrushWellman or NGK Berylco.
