China Best Chromium Copper Alloy for Making Molds

Chromium copper has begun to replace beryllium copper as a general mold material in the mold industry due to its conductive and thermal conductivity, hardness, wear resistance and explosion resistance, and superior price compared with beryllium copper mold material. For example, shoe sole molds, plumbing molds, plastic molds that generally require high smoothness, connectors, guide wires, and other products that require high strength wires.

At room temperature and higher temperature (400 ° С) It has high strength and hardness, good electrical conductivity and thermal conductivity, good wear resistance and antifriction. After age hardening treatment, the strength, hardness, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld and braze. It has good corrosion resistance in atmosphere and fresh water, good high-temperature oxidation resistance, and can withstand pressure processing in cold and hot states, but its disadvantage is that it is sensitive to notch, Stress concentration at notch and sharp corner is easy to cause mechanical damage. Therefore, it is not suitable to make commutator slices.
