Resistance tolerance

Standard resistance tolerance for wire is listed in the following table. Wire can be supplied to closer tolerance on request.
The data is valid at 20°C (68°F).

Wire size Ø mm (inch) Resistance tolerance %
<0.127 (0.005) +/- 8
>0.127 (0.005) +/- 5

Delivery forms

Kanthal® resistance wire is delivered on spools, in coils, in pail pack or as straightened lengths.

Insulation and coating

The Kanthal® program includes a wide range of insulation coatings, bondable coatings and metallic coatings such as electroplating and anodizing. All coatings are available in various colors.

Marking

Each spool/package of wire is supplied with a label or tag showing alloy type, nominal size, tara and net weight, resistance W/m (W/ft), charge number and a reference number.
