Product Description

Nickel-chromium materials are widely used in industrial electric furnaces, household appliances, far-infrared devices and other equipment due to their excellent high temperature strength and strong plasticity. Nickel-chromium and iron, aluminum, silicon, carbon, sulfur and other elements can be made into nickel-chromium alloy wire, which has high resistivity and heat resistance and is the electric heating element of electric furnace, electric soldering iron, electric iron and other products.

In addition, NiCr wire is usually used in the coil of sliding rheostat to protect the circuit and change the current in the circuit by changing the resistance of the access circuit part, thereby changing the voltage across the conductor (electrical appliance) connected in series with it, It is widely used in a large number of household appliances.
