Beryllium copper alloys generally have a beryllium content of up to 2.7% depending on the intended application
Beryllium copper which is also known as beryllium bronze and spring copper, offers the highest strength of any copper currently available on the market.
Alloying elements such as nickel and cobalt are also added to improve specific properties such as heat treatment performance. The alloy displays an excellent response to precipitation hardening - when heat treated this range of alloys exhibit high strength and hardness and these properties combine with thermal and electrical conductivity, as well as good corrosion resistance to make beryllium copper a very useful material.
Applications for beryllium copper usually divide between those requiring high strength and those requiring high conductivity. For applications requiring high strength alloys with a higher beryllium content, either a precipitation hardening heat treatment or an age hardening process is recommended. For applications requiring high conductivity, alloys with lower beryllium content are used (down to around 0.7%).
Alloys are usually supplied in the soft condition to enable cold working and machining before heat treatment of the finished component. Beryllium copper is also non-magnetic and non-sparking, a characteristic that makes it particularly suitable for use in explosive atmospheres (tools etc).
