    Product Tags

    Nickel-Chromium Alloys are characterized by high resistivity, good oxidation resistance and very good form stability. They have good ductility after using and excellent weldability.
    NiCr alloys are used for making electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
