Product overview Enameled wire, also known as insulated copper wire, features a pure copper core and a surface insulating coating. This pack includes 1 x enameled wire weighing 500 g (17.6 oz). The coating is a polyester enamel finish, giving durable insulation while remaining pliable for winding and magnetics work. Key benefits It is compatible with direct welding: the insulation coating enables you to solder or weld windings directly without removing insulation. It is ready for frequency applications: designed to perform well in frequency applications with reliable insulation. It is portable and easy to handle: the 500 g pack is convenient for hobbyists, technicians, and small shops. It has clear specification alignment: color coding (where shown) corresponds to wire diameter and follows national standard copper wire specifications. Materials and construction Core material: pure copper Insulation: polyester enamel coating with a surface insulating paint Outer finish: polyester patent leather style coating as described Electrical and thermal performance Withstand voltage: 3000 to 5000 V Temperature range: 130 to 180 degrees Celsius Specifications and references Color classification indicates wire diameter (the specification). The copper wire adheres to national standard specifications. Specification refers to the diameter of the drawn copper wire, i.e., the inner diameter before the paint film is applied. Use scenarios Transformer or inductor winding in electronics projects: use this wire for coils that require good insulation and solderability. frequency assemblies and RF circuits: suitable for winding coils and components that operate at higher frequencies. DIY and work: handy for small motors, relays, NFC/RF coils, and repairing wound components where insulation must remain intact. Notes on compatibility and handling It is suitable for direct welding on the copper core where insulation remains intact, supporting efficient assembly in appropriate applications. Ensure proper handling and storage to maintain insulation integrity and avoid physical damage to the coating.
