High Quality Chromium Copper Alloy for Making Molds

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.

Chromium copper, at room temperature and higher temperature (400 ° С) A material with high strength and hardness, good conductivity and thermal conductivity. Chromium copper has the advantages of good conductivity and heat conductivity, high hardness, wear resistance and explosion resistance, good upright performance, no bending when thinned, and high smoothness when used as an electric spark electrode.
