Ni80Cr20 - is an austenitic nickel-chromium alloy suitable for temperature applications up to 1230°C.
This alloy provides extraordinary performances at temperatures up to 1200°C and offers superior operation life compared to other nickel-chromium alloys.
Ni80Cr20 is characterized by high resistivity, good oxidation resistance (especially under conditions of frequent switching or wide temperature uctuations), very good form stability, good ductility after use and excellent weldability.
Ni80Cr20 is used for electric heating elements in home appliances and industrial furnaces. Typical applications are: irons, water heaters, heavy duty resistors, tubular elements, electric cooking equipment, heating batteries, electric furnaces, etc.
