Beryllium Copper Wire for Custom Springs & Custom Wire Forms
Please note that we do not sell Beryllium copper or any other materials in raw form. Beryllium copper wire is a material option for custom springs, etc., manufactured by Peninsula Spring.
Beryllium copper offers numerous beneficial properties, including good strength, high electrical conductivity, and high thermal conductivity. It is non-magnetic and can be heat-treated for additional hardness. Although more costly than high-carbon and alloy steels, beryllium copper alloys are much better suited to, and preferred for, electrical applications.
One of the key advantages of Beryllium copper to fabricate custom springs and wire forms is that the material can be formed in a soft state. Additionally, it can be age hardened to improve its spring properties.
Once age hardened, Beryllium Copper C172 (Alloy 25) attains the highest strength and hardness of any common commercial copper alloy. Beryllium copper alloys’ high conductivity makes them ideal for applications that require high operating temperatures, high strength, and/or high conductivity.
