Nichrome Cr20Ni80 Cr10Ni90 Cr15Ni60 Cr30Ni70 Cr20Ni30 Electric Heating Resistance Wire Coil For Vapes
NiCr Series
Cr20Ni80 is an ideal material, it has good ductility,workability and weldability under high temperature and seismic strength. Nickel-chromium alloy with high and stable resistance, corrosion resistance, surface oxidation resistance, excellent coil-forming ability.
Nichrome wire is made of a non-magnetic alloy composed primarily of nickel, chromium, and iron. It is characterized by its high resistivity and good oxidation resistance. Nichrome wire also has good ductility after use and excellent weldability.
All these properties make it possible to use nichrome wires and strips for the manufacture of heating elements in laboratory and industrial electric furnaces, various electrical devices of thermal action, for example, in heat guns and industrial hair dryers, as well as water heating systems, high-value electrical resistors, heating cords and cables.
