Ni35Cr20 is an austenitic nickel-chromium alloy suitable for
temperature applications up to 1100°C. This alloy is characterized
by high resistivity, good oxidation resistance, good ductility
after use and excellent weldability. Ni35Cr20 is used for a wide
range of electric heating elements in domestic appliances.
Typical applications: hot plates, heavy-duty rheostats, storage
heaters, convection heaters, fan heaters, heating cables, electric
blankets and pads, car seats, resistors, etc.
