Product Description
Our Copper-Chromium (CuCr) master alloy is manufactured in China using advanced vacuum induction melting technology with precisely controlled composition. This master alloy is designed for electrical contact materials, resistance welding electrodes, and high-conductivity wear-resistant alloy manufacturing, providing exceptional grain refinement, strength enhancement, and processability improvements in target alloy systems.
- Optimized chromium content (5-10%) for balanced conductivity and mechanical strength in CuCr alloys
- Provides excellent wear resistance and arc erosion resistance in electrical contact applications
- High recovery rate (≥95%) ensures cost-effective and predictable alloying results
- Fine and uniform Cr dispersion in copper matrix achieved through controlled solidification process
- Widely used in medium-voltage vacuum interrupters, resistance welding electrodes, and lead frames
