The Element Copper-Chromium (Cucr)

The Element Copper-Chromium (Cucr)

The word copper is derived from the Latin word ‘cuprum’ meaning ‘metal of Cyprus’ because the Mediterranean island of Cyprus was an ancient source of mined copper. The element symbol Cu also comes from ‘cuprum.

Used in large amounts by the electrical industry in the form of wire, copper is second only to silver in electrical conductance. Copper ensures the excellent electrical and thermal conductivity of the contact material. Moreover, the combination of copper and chromium (Cucr) offers outstanding performance due to the following properties:

  • Mechanical strength
  • Low gas content
  • Excellent arc erosion resistance
  • Very good dissipation of short-circuit currents
  • Low welding tendency
  • Economical production of near-net shapes
  • Breaking capacity of up to 63 kA
  • Maximum chopping current < 6A

Copper-chromium (Cucr) master alloy has the main characteristics of copper, which is a soft, conductive, non-ferrous metal. Copper is also resistant to corrosion and ductile. Modison is one such company that manufactures various copper and copper alloys elements.
