Heat treatment copper-beryllium

Technical data & advantages

A 3 hours heat treatment at 315 °C under protective atmosphere will increase the hardness up to about 400 Vickers
Structural hardness, hardening is done with minimum deformation
Spring effect on the material
Plating applied soon after heat treatment avoid surface aging problems (oxidation)
For customer, only one partner for heat treatment and metal finishing (plating)

Main applications

Watches : Components for the movement
Mechanic : CuBe parts that need a certain hardness, spring function
Electronic : Switches, spring contacts

Very important observation

Before applying heat treatment, parts must be supplied in a state of complete cleanliness ; residues on the surface will results in corrosion (etching) of substrate.
