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.
