Resistance heating strip

Resistance heating strip for furnace heating elements and other heat-generating applications. The strip is normally delivered in cold-rolled condition with ground surface.

Our wide range of resistance heating alloys in strip form makes it possible to select the most appropriate grade and size for each respective application, resulting in optimum end-product performance. The consistent resistivity from delivery to delivery facilitates trouble-free production.

Size range

Thickness: 0.10-4 mm (0.00394-0.157 inch)
Width: 4-200 mm (0.157-7.874 inch)
Other sizes can be delivered on request.

Resistance heating alloys in strip form

Type of alloy Description
Kanthal and Alkrothal FeCrAl alloys* High-resistivity iron-chromium-aluminium alloys for use up to 1400ºC (2550ºF).
Nikrothal NiCr alloys High-resistivity nickel-chromium alloys for use up to 300ºC (570ºF).
Cuprothal CuNi alloys Medium- and low-resistivity copper-nickel alloys for use up to 150ºC (300ºF).

* Kanthal FeCrAl alloys are available as both conventional alloys and powder metallurgical alloys (Kanthal APM).

Resistance tolerance

Standard resistance tolerance for strip is ± 5%, but strip with closer resistance tolerance can be delivered on request.

Delivery forms

Kanthal resistance heating strip is supplied in coils with an internal diameter of Ø 400 mm or in straightened lengths.


Each coil of strip is supplied with a label or tag showing alloy type, nominal size, tara and net weight, resistance Ω/m (Ω /ft) and charge number
