Description

2.0855 (CuNi2Si) is a precipitation hardening copper nickel silicon that offers a remarkable blend of physical and mechanical attributes unrivalled by many other grades of copper alloy. Colsibro® is a high copper alloy with small additions of nickel and silicon, which combine to increase the strength, hardness and wear resistance of the material, while retaining many of the physical benefits of copper itself. It shows the following features and properties:


  • Excellent corrosion resistance, surpassing many copper alloys, with complete freedom from stress corrosion
  • High strength and hardness
  • Very good wear resistance and bearing properties
  • Excellent thermal and electrical conductivities compared to most non-ferrous alloys
  • Outstanding cryogenic properties and an exceptionally low magnetic permeability
  • Complete freedom from hydrogen embrittlement
  • Spark resistance
  • Related Standards
