Beryllium bronze is a bronze with beryllium as the main additive element. The beryllium content of beryllium bronze is 0.2%~2%, and a small amount of cobalt or nickel (0.2%~2.0%) is added. The alloy can be strengthened by heat treatment. It is an ideal elastic material with high conductivity and strength. Beryllium bronze is non-magnetic, spark resistant, abrasion resistant, corrosion resistant, fatigue resistant and stress relaxation resistant. And it is easy to cast and press forming.

Beryllium bronze castings are typically used as molds for plastics or glass, resistance welding electrodes, explosion-proof tools for oil mining, submarine cable shields, etc.
Beryllium bronze processing materials are typically used as current carrying springs, connectors, contacts, fastening springs, leaf springs and spiral springs, bellows, lead frames, etc. in electronic devices.
