Copper Magnet Wire Make A Good Function

  • Befor to understand copper magnet wire,ask you a question.What is the difference between copper wire and magnet wire?

    Copper is used in motor windings, transformer windings, induction coils, The insulation may be a thin film of varnish called enamel, a fibrous polyester or fiberglass yarn; or a combination of both enamel and fibrous insulations. The fibrous insulation may be impregnated with a varnish to bind the insulation to the conductor and enhance thermal endurance. If it is bare copper then, windings will result in short circuit, so an enamel coat is applied which acts as insulator & makes winding possible. This is done by making the copper dip in to enamel solution as it is “drawn” to required thickness / diameter and allowed to cure. Such enamelled / insulated copper wire is called magnet wire.

    However, Bare copper is used in electrical wiring & connections including grounding / earthing.

    Magnet wire is also called winding wire. There are a number of film insulation types ranging from temperature Class 105 to Class 240. Each film type has its own unique set of characteristics to suit specific needs of the application

    Magnet wire shelf life is not established in commercial specifications. As long as the wire has been carefully stored it may be usable for years to come. Bondable wire should not be stored at temperatures exceeding 100°F. Electrolytic tough pitch copper (ETP Copper, UNS C11000) exceeds 99.9% purity and is the most widely used type for magnet wire production. It is intentionally oxygenated (200-400 ppm) to achieve the best combination of conductivity, capacity for being cold worked and economy. MWS can also supply wire made from high purity (99.95%) OFHC Copper (UNS C10200) or Certified (99.99%) OFHC Copper (UNS C10100).
