Main chemical composition of nickel-chromium wire is nickel and chromium. Also written as Nichrome wire. Ideal heating resistant material with good ductility,workability and weldability under high temperature and seismic strength. Also known as electric heating wires or heating resistant wire, popularly used as electric heating element.
Popular Nickel-chromium Alloy Wire Type:
Nickel-chromium alloy grades: Cr20Ni80, Cr15Ni60, Cr20Ni35, Cr20Ni30.
Hydrogen Annealing Cr20Ni30 Nickel Chromium Wire for Stove Coil Heating Wire is very popularly used.
