Applications:

• 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.
