    NiCr Wire High Electrical Resistance Melting Point Nichrome Wire for Slide Rhostat

    1.Brief introduce
    Nichrome wire is constructed from an alloy made from nickel (Ni), chromium (Cr), and often iron, primarily it is used as a resistance wire. It is widely used in home appliances and industrial heat treatment area.

    2.Feature of NiCr Alloy
    (1)High resistance
    (2)Low temperature coefficient of resistance
    (3)High working temperature
    (4)Good corrosion resistance especailly under high temperature

    (5)Good performance of anti-carburizing, the atmosphere and surface of sulfur pollution.
    (6)Long useful life
    3. Advantages of NiCr alloy
    (1)Good corrosion resistance at high temperature.
    (2)The price is cheaper than Nickel Chrome wire.
    (3) It can be widely used in industrial furnacess, household appliances and far-infrared devices.


    4. The application of NiCr wire
    NiCr heating wire is widely 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.

    5.Application in Resistor
    A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. The construction is very similar to the construction of a potentiometers. It uses only two connections, even when 3 terminals (as in a potentiometer) are present. The first connection is made to one end of the resistive element and the other connection to the wiper (sliding contact). In contrast to potentiometer, rheostats have to carry a significant current. Therefore they are mostly constructed as wire wound resistors. Resistive wire is wound around an insulating ceramic core and the wiper slides over the windings.
