Nikrothal 80 is an austenitic 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.
Nikrothal 80 is used for 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.
Due to extremely good adhesion properties of the surface oxide, Nikrothal 80 offers superior service life compared to competitive nickel-chromium alloys.
