Chromium Zirconium Copper (CuCrZr)


Chromium Zirconium Copper (CuCrZr)


  • C18150


  • Zirconium addition to chromium copper improves creep resistance at high operating temperatures and reportedly reduces sticking of electrodes to the work during spot welding of galvanized materials.
  • Popular as moulds and dies for continuous casting due to its excellent electrical and thermal conductivity, hardness and ease of fabrication
  • Low toxicity with excellent mechanical wear resistance and high radiation resistance
  • Used extensively as electrodes in resistance welding and as circuit breakers in the electrical sector and also as rod extensions for seam and spot welding.
