Main Advantage and Application
It widely used in surtur and sulfide environment and producing industrial electric furnace, household electrical appliance and far infrared ray device.
Low price with high electric resistance, low temperature cofficient of resistance, high working temperature and good corrosion resistance under high temperature especially.
Size
wires:0.018-10mm Ribbons:0.05*0.2-2.0*6.0mm
