Beryllium Copper Sheet & Strip for Custom Springs and Stampings

Please note that we do not sell Beryllium copper or any other materials in raw form. Beryllium copper sheet and strip are material options for custom springs, etc., manufactured by Peninsula Spring.

Beryllium copper exhibits many desirable properties, such as good strength and high thermal and electrical conductivity. The material is non-magnetic and heat-treatable. Although they’re more expensive than high-carbon and alloy steels, beryllium copper alloys are preferred for electrical applications.

A key advantage of using beryllium copper to produce custom springs and stampings is its ability to be formed in a soft state. It can then be age hardened to achieve spring properties.

In its age hardened condition, Beryllium copper C172 (Alloy 25) attains the highest strength and hardness of any commercial copper base alloy. The high-conductivity of beryllium copper alloys is ideally suited to applications requiring high operating temperatures, high strength, and/or high conductivity.

Age Hardening Beryllium Copper

  1. Heat to 600-625°F (316-329°C)
  2. Hold for 2-3 hours (depending on initial temper)
  3. Air cool to room temperature
  4. Results in full hard temper

Manufacturing Custom Beryllium Copper Springs & Stampings

Beryllium copper exhibits good corrosion resistance, electrical conductivity, and moderate spring properties. The material is cold drawn to the specified temper. After fabrication, beryllium copper may be age hardened for improved spring properties.
