Enameled copper wire with a pure copper core and a surface enamel coating, finished with a polyester patent leather layer. This product is packed as 1 x enameled wire (500 g / 17.6 oz). Key benefits Direct weldability: can be soldered/ welded directly without removing the enamel coating. frequency performance: designed to resist frequency conditions, suitable for RF and coil applications. Portable and easy to handle: compact packaging and manageable weight. National standard and clear sizing: color coding corresponds to wire diameter and uses national standard specifications for copper wire. Specifications and construction Model/Product type: enameled wire (insulated copper wire) Core material: pure copper Surface coating: enamel with polyester patent leather finish Packing: 1 x enameled wire (500 g / 17.6 oz) Voltage withstand capability: 3000 V to 5000 V Temperature range: 130 to 180 degrees Celsius Color classification: indicates wire diameter (specification); copper wire adheres to national standard specifications Specification reference: refers to the diameter of the drawn copper wire, i.e., the inner diameter without the paint film Material and compatibility Core material: copper Enamel/coating: enamel with polyester patent leather finish Match with standard copper wire specifications and coil winding practices Use scenarios Transformer and inductor winding: suitable for small to medium transformers and inductors that require reliable enamel insulation and good frequency performance. RF coils and electromagnets: effective for frequency applications where stable insulation and solderability are important. DIY electronics and repairs: useful for hobby projects, winding custom coils, or repairing magnetic components. Notes on specifications The color shown in listings corresponds to the wire diameter (specification). The copper wire itself follows national standard specifications. The specification refers to the diameter of the drawn copper wire, i.e., the inner diameter before the enamel coating.
