Fine wire in stainless steel and precious metals
Our resistance fine wire program is the largest on the market and is mainly Kanthal® alloys. Kanthal® is the trademark for resistance and conductive alloys within Alliema and offered in various product forms where wire is one.
We offer a broad selection of CuNi, NiCr, FeCrAl, NiFe and various thermocouple resistance alloys in sizes from 0,01 mm to 0,82 mm (0.0004” to 0.032”), the right alloy at the right resistance is available from our facility.
Our resistance wire is either drawn to size, or to resistance. Every item is made to order, and built to the specific requirements of your application with close attention to the exacting details of your requirement. The wire is available with or without insulation or coating.

>0.127 (0.005) | ±5 |
Our fine resistance wire can be supplied on spools, in coils, in pail pack or as straighened lengths.
The fine resistance wire 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. Read more about insulations and coatings.
Each spool/package of wire is supplied with a label or tag showing alloy type, nominal size, tare and net weight, resistance W/m (W/ft), charge number and a reference number.
