Technical Article: Introduction of Nickel-Chromium Wire

Nickel-chromium wire (Cr20Ni80)

1. The resistivity is small, the high temperature strength is high; the welding and processing performance are good; the mechanical properties at high temperature do not change greatly.

2, the maximum use temperature: 1000-1050 degrees Celsius

3. After the high temperature of 1050 degrees, the toughness is good and it is not easy to be brittle.

4. The rate of change of resistance after high temperature is generally 6-8%. The power is relatively stable during use.

5. Generally, high temperature heating tubes are produced using nickel-chromium wire. It mainly contains nickel and chromium components, which is not easily oxidized at high temperatures and has a long service life.
