    Fe-Cr-Al alloy wires are made of iron chromium aluminum base alloys containing small amounts of reactive elements such as yttrium and zirconium and produced by smelting, steel rolling, forging, annealing, drawing, surface treatment, resistance control test, etc.
    The high aluminum content, in combination with the high chromium content let the scaling temperature can reach to 1425ºC (2600ºF);
    Fe-Cr-Al wire was shaped by means of high speed automatic cooling machine of which the power capacity is controlled by computer, they are available as wire and ribbon(strip).

    Application
    Our products (FeCrAl) high resistance electric heating wire materials are salable and widely used for making heating equipment like industrial furnace, civil heating appliance, various electrical resistors and locomotive braking resistor, infrared equipment, liquefied gas infrared heat-resisting net, different kinds of igniting and radiating electrodes and voltage-regulating resistors for motors and so on in Metallurgical machinery, medical, chemical, ceramics, electronics, electrical appliances, glass and other civil or industrial fields.


    Features and advantages
    1. High using temperature, the maximum using temperature can reach 1400C (0Cr21A16Nb, 0Cr27A17Mo2, etc.)
    2. Low temperature coefficient of resistance
    3. Lower thermal expansion coefficient than the Ni-base super-alloys.
    4. High electrical resistivity
    5. Good corrosion resistance under high temperature, especially under the atmosphere containing sulfides
    6. High surface load
    7. Creep-resistant
    8. Lower raw-material cost, Lower density and cheaper price compared with Nichrome wire.
    9. Superior oxidation resistance at 800-1300ºC
    10. Long service life

    Product forms and size range
    Round wire
    0.010-12 mm (0.00039-0.472 inch) other sizes are available on request.
    Ribbon (flat wire)
    Thickness: 0.023-0.8 mm (0.0009-0.031 inch)
    Width: 0.038-4 mm (0.0015-0.157 inch)
    Width/thickness ratio max 60, depending on alloy and tolerance
    Other sizes are available on request.
    Resistance electric heating wire has strong antioxidant properties, but a variety of gases in furnaces such as air, carbon, sulfur, hydrogen and nitrogen atmosphere, still have a certain impact on it.
    Although these heating wires all have had antioxidant treatment, the transportation, winding, installation and other process will cause damage to a certain extent and reduce its service life.
    In order to extend the service life, customers need to do pre oxidation treatment before using. The method is to heat alloy elements which have installed completely in the dry air to the temperature (lower 100-200C than its maximum using temperature), heat preservation for 5 to 10 hours, then cooling slowly with furnace.
