Cr20Ni80 Alloy Wire With High Nickel Content For Excellent High Temperature Resistance
Introduction:
Cr20Ni80 alloy wire is a high-temperature alloy wire, mainly composed of 20% chromium and 80% nickel. It has good high temperature resistance and can provide stable resistance characteristics in high temperature environments. This alloy wire is widely used in electric furnace heating elements, resistance welding, heaters, hot mist generators and other fields.
