Copper Beryllium

Copper Beryllium

Form of supply:

Copper Beryllium is a copper alloy with a optimum combination of mechanical and physical properties such as tensile strength, performance under elevated temperatures, electrical conductivity, ebding formability and corrosion resistance. Copper Beryllium is widely used as contact springs in various applications line connectors, switches, relays, etc. NGK offers a variety of Copper Beryllium alloys in several tempers to cover different applications. Their Copper Beryllium products are available in Strip, plate, rod and wire form.

  

Tensile Strength

Copper Beryllium can attain the tensile strength 1500N/mm2 through precipitation hardening and can withstand very high bending stress.

Bending Formability

Age hardenable material can be formed into complicated shape and precipitation hardened afterwords. Among Mill-hardened material, which does not require heat-treatment after stamping or forming, ‘Type-B’

Fatigue Strength

Because Copper Beryllium exhibits excellent resistance to fatigue, it is also used in components where a longer life in service with a cycle stress environment is needed.

Electrical Conductivity

The electrical conductivity of beryllium Copper ranges from 20 to 70% IACS, depending on alloy and temper. Copper Beryllium is often used as a high current density spring material.

Thermal Stability

Due to less stress relaxation at elevated temperature Copper Beryllium can be used in a wide range of temperatures with little loss of mechanical properties.

Corrosion Resistance

Copper Beryllium has excellent corrosion resistance, nearly the same as Nickel Silver.
