Width: 4-200 mm (0.157-7.874 inch)
Other sizes can be delivered on request.
Standard resistance tolerance for strip is ± 5%, but strip with closer resistance tolerance can be delivered on request.
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
