These magnet wires, which are formed by coating copper wires, with various insulating materials, convert electric energy into magnetic energy. Their heat resistance grade depends on the type of insulating resins; large coils are used for power generators while smaller coils are used for small high-performance motors for electric appliances. The field of electronics is advancing so rapidly that the needs for magnet wires are changing day by day. Using the material, design, processing technologies backed by more than 110 years of experience, Furukawa Electric is continuously developing high-quality magnet wires with excellent cost performance.
