Product details

Beryllium copper

Beryllium as the main alloying element of copper alloy, also known as beryllium bronze.It is the best performance of copper alloy in the advanced elastic material, has a high strength, elasticity, hardness, fatigue strength, small elastic lag, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic, impact does not produce spark and a series of excellent physical, chemical and mechanical properties.

Whole series of beryllium copper are referred to as "the king of non-ferrous metal elastic, meeting the requirements of all kinds of high strength, high elasticity, high hardness, high wear resistance of the micromotor brush, switch, relay, connectors, spring piece of thermostat, all kinds of leaf spring, with the requirements of the product's reliability, service life is higher and higher, beryllium copper demand will be greater and greater.
