Beryllium Copper

High Strength and Electrical Conductivity to Reduce Dimensions

Beryllium copper combines the high electrical conductivity, high thermal conductivity, and ease of machining of copper with the high strength and spring properties of beryllium. With the addition of 0.5% to 3.0% beryllium to copper, this alloy offers strength comparable to special steel. Iwatani supplies beryllium copper for applications in advanced fields that help achieve the SDGs and establish a decarbonized society.

Product Characteristics

1Tensile Strength

Max. 1,500 N/mm2

2Electrical Conductivity

Approx. 20% to 70%IACS

3Ease of Machining

Highly machinable; suitable for precise machining.

4Fatigue Resistance

Aging boosts fatigue resistance to extend product service life.

5Heat Resistance

Suitable for use in high temperature environments due to good stress relaxation resistance

6Corrosion Resistance

Offers excellent corrosion resistance, second only to copper-nickel-zinc.
