Nikrothal® 60 wire is an austenitic nickel-chromium alloy (NiCr alloy) for use at temperatures up to 1150°C (2100°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® 60 is used in electric heating element material in domestic appliances. Typical applications are metal sheathed tubular elements used in, for example, hot plates, grills, toaster ovens and storage heaters. The alloys is also used for suspended coils in air heaters in clothes dryers, fan heaters, hand dryers.
