Cr20Ni80 Nichrome Resistance Wire High Resistance Oxidation Resistance Bright Annealed Nickel Chrome Alloy Wire

Cr20ni80 Nichrome Resistance Heating Wire Nickel Chrome Alloy

NiCr80/20

Cr20Ni80, also known as Ni80Cr20, is a nickel-chromium resistance alloy consisting of approximately 80% nickel and 20% chromium. It is widely used in electric heating elements due to its excellent oxidation resistance, stable electrical resistivity, and high-temperature performance.

Cr20Ni80 strip is suitable for manufacturing industrial heating elements, electric furnace components, household appliances, and various resistance devices operating at elevated temperatures. The alloy maintains good mechanical strength and long service life under continuous heating conditions.
