FeCrAl 0Cr25Al5 Fecral Wire Resistance Heating Wire for Civil
Heating Appliance
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.
