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.
NiCr Alloy Series
Ni90Cr10 strip is kind of nickel-chromium alloy products, it is suitable for temperature applications up to 1250°C. Chromium content provides very good life time, it is usually used as a vape heating element.
Ni90Cr10 is characterized by high resistivity, good oxidation resistance, good ductility after use and excellent weldability. NiCr Alloy is a good material for heating industry.
