Supply forms
Round wire, ribbon, spool, coil, or cut length — and the enamelled variant where the winding needs insulation.
Bare conductor
| Form | Size | Packing |
|---|
| Round wire | 0.10 – 10.0 mm | Spool, coil, or cut length |
| Ribbon | To drawing | Coil or cut length |
| Surface | Bright or oxidised | As the winding process requires |
Enamelled
| Grades | CuNi1 to CuNi44, CuMn12Ni |
| Enamel | Polyurethane (UEW) |
| Diameter | 0.05 – 1.0 mm |
| Used for | Precision resistors, wound components, sensors, heating-cable conductors |
Spool and coil
| Packing | Used for |
|---|
| Spool | For fine wire that feeds a winder directly |
| Coil | 5 / 10 / 20 kg standard, for cutting at the customer’s end |
| Cut length | Straightened and cut to the element length |
Marking
- Batch number on the spool or coil tag
- Grade and measured diameter
- Measured resistivity for the lot
- Net weight
