Direct-welding enameled copper wire — 0.3mm diameter, 500g

Composition: Direct-welding enameled copper wire with an internal copper conductor coated in surface insulating paint and finished with polyester patent leather. Size & weight: 0.3mm diameter, 500g. Key qualities: resilient and durable — resists breakage during winding and maintains a natural copper color. Welding advantage: enamel formulation permits direct welding without scratching the isolation layer, simplifying joint work. Function: as magnet wire it converts electrical current into magnetic fields. Typical applications: building transformers, inductors, motors, solenoids, electromagnets, speaker coils and speakers, potentiometers, winding coils, inductive coils and other insulated wire coil assemblies.
