Magnet Wire


Magnet Wire (Enameled Wire) is the core material for electromagnetic devices such as motors, transformers, and inductor coils. It features high-purity oxygen-free copper conductors coated with multiple layers of high-temperature resistant enamel insulation, maintaining stable electrical insulation performance and mechanical strength across a wide temperature range of -65°C to +220°C.

The insulation system utilizes high-performance coatings including Polyesterimide, Polyamide-imide, or Polyimide, offering excellent heat resistance, chemical corrosion resistance, and abrasion resistance. The enamel film exhibits strong adhesion, resisting detachment during high-speed winding operations to ensure flawless insulation integrity after coil forming. The conductor surface is highly polished with stable resistivity, significantly reducing eddy current losses and improving electromagnetic conversion efficiency.

This magnet wire is suitable for various high-frequency transformers, power inductors, motor windings, relay coils, and precision electromagnetic components, widely applied in new energy vehicle drive motors, industrial frequency converters, aerospace electronic equipment, and premium household appliances.
