Beryllium copper is a highly ductile copper alloy that, depending on the beryllium content, can be used for a number of applications.

One of the prime applications of CuBe is for producing springs that need to hold shape and function when subjected to repeated use in severe conditions. In comparison to spring steel, copper beryllium is non-magnetic, so can be used in areas where steel is not applicable. Another major advantage is that springs can be formed in a soft condition and then precipitation hardened to spec.

Other important uses include:

• non-sparking tools and components
• fasteners
• low-current contacts and electronic connectors
• diaphragms for pressure-sensitive instruments
• dies for moulding plastics

Heat treatment produces a state of high electrical conductivity, high strength and hardness, elasticity, and corrosion resistance. Treatment is a two-step process: softening by quenching from a high temperature and then hardening by heating to a moderate temperature. It is also possible to cold work beryllium copper--or combine cold working with heat treatment to achieve the desired result.

This very versatile and workable alloy should never be rejected because of cost concerns. The superior nature of copper beryllium, and it's ability to be formed to exact requirements can lead to great overall savings in production time and customer rejects.

M Vincent and Associates stocks and sources beryllium copper in the following grades: C170 • C172 • C173 • C175 • C17510.

*It is important to note that  beryllium mist, dust, and fumes are a known health hazard. Safety precautions should be taken when working with CuBe. More information can be found at the OSHA website.
