China Micc Nicr8020 Nichrome Wire 032 Resistance Wire

MICC Nicr8020 Nichrome Wire 0.32 Resistance wire
Our resistance wire(heating wire) has the characteristics of high rate of resistance, small resistance temperature coefficient and high use temperature. It has a good corrosion resistance at high temperature, low price and is particularly suitable for using in the atmosphere of sulfur and sulfide, so it is an ideal heating material used in industrial furnaces, household appliances and far-infrared devices.
