Product Description
FeCrAl 0Cr21Al6Nb Alloy Strip Resistance Heating Flat Wire with ISO9001 Certificate
Introduction
Resistance 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.
