Bright Nichrome Heating Resistance Alloy Wire Ni30Cr20

Bright Nichrome Heating Resistance Alloy Wire

• NiCr Series

Ni30Cr20 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.
