Description:
Nichrome Grade: Ni70Cr30,Ni80Cr20, Ni60Cr15, Ni35Cr20, Ni30Cr20
Description:
Ni80Cr20 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.
Ni80Cr20 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.
