Description:
Cr20Ni80 is a nickel-chromium alloy (NiCr alloy) for use at temperatures up to 1200°C (2190°F). The alloy is characterized by high resistivity, good oxidation resistance and very good form stability. It has good ductility after use and excellent weldability.
Cr20Ni80 is used for making electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.

Application of nichrome alloy wire
:
A Resistance Alloy used in electrical heating application. It is recommended for use in dry air applications up to 2150 degrees F with good hot strength. It is an alloy of nickel and chromium with high electrical resistance; used for resistance heating elements. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath the wire will not oxidize, preventing the wire from breaking or burning out.
Applications:
- These elements are commonly found in precision heating applications such as Medical Diagnostics, Satellite, and Aerospace
- Electrical appliance industry
- Ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements, cartridge elements
