Product Feature
Based on chromium and zirconium characteristics, the hardness, strength, electrical conductivity and thermal conductivity of the alloy are significantly improved by aging heat treatment.
The products are easy to weld, have good wear resistance and wear reduction, widely used in motor commutator, spot welder, seam welder, electrode for butt welder, and other high temperature requirements of strength, hardness, electrical conductivity, pad parts.
Typical Application
The alloy is widely used in automobile, vehicles, agricultural machinery, ships, aerospace, civil electrical appliances TV, refrigeration equipment, washing machines and other products of electric resistance welding (spot welding, seam welding, seam welding, butt welding, CO2 protection welding), such as welding electrodes and the metallurgy continuous casting crystallizer, motor, power distribution equipment and high-speed train with sliding connection, etc.
