Resistance heating wire and conductive wire
Wire in a wide range of alloys optimized for use in, for example, resistance, high-temperature and conductive applications.
Round and flat resistance heating wire and resistance wire with bright annealed or oxidized surface, depending on size. Round resistance wire sizes up to 0.40 mm (0.0157 inch) are available with insulation and coating.
Information
Product forms available are:
- Round wire
- Flat wire (ribbon)
- Shaped wire
The wire is supplied on spools, in coils, in pail pack or as straightened lengths and available with or without coating.

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.
