nicr alloy wire
Resistance Heating Wire includes pure nickel, chromel alloy, Fe-Cr-Al alloy and copper nickel alloy. Resistance heating wire is produced by smelting, steel rolling, forging, annealing, drawing, surface treatment, resistance control test, etc. It is widely used for making heating equipment like industrial furnace, civil heating appliance, various electrical resistors and locomotive braking resistor.
