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. Main characteristics of FeCrAl high
