Resistance heating wire and strip

Resistance heating wire and resistance heating strip in iron-chromium-aluminium (FeCrAl) alloys and nickel-chromium (NiCr) alloys for the manufacturing of electric heating elements.

Using Kanthal FeCrAl alloys instead of NiCr alloys result in both weight-saving and longer element life. Compare Kanthal FeCrAl alloys with NiCr alloys

Kanthal and Alkrothal FeCrAl resistance heating alloys

Resistance heating alloys based on iron-chromium-aluminium for maximum element temperature of 1425°C (2600 °F). Kanthal and Alkrothal resistance heating alloys are characterized by high resistivity and capabiltity to withstand high surface load.

Nikrothal NiCr resistance heating alloys

Nickel-chromium-based resistance heating alloys suitable for element temperatures up to 1250°C (2282°F). Nikrothal resistance heating alloys are characterized by very good mechanical properties in the hot state as well as good oxdiation and corrosion properties.

Product forms and size ranges

Kanthal resistance heating alloys are available in the following product forms and sizes:

  • Round wire: 0.10-12 mm (0.00394-0.472 inch)
  • 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/thickess ratio max 40, depending on alloy and tolerance
  • Strip: thickness 0.10-5 mm (0.00394-0.1968 inch), width 5-200 mm (0.1968-7.874 inch)
    Other sizes are available on request.
