Copper Magnet wire

Copper magnet wire is copper wire coated with one or more thin layers of insulating enamel, creating a conductive material capable of insulating between coil turns. It is an irreplaceable material in the production of electric motors, transformers, inductors and electromagnetic devices.

LiOA Copper produces magnet wire from in-house drawn copper wire, coated with polyester, polyurethane, or polyamide-imide based on heat class.
