Product Description
Magnet wire is one of the core materials in manufacturing heavy electric products, home appliances, and automobile parts. It is usually wound in the form of a coil inside the electric device and converts electric energy into kinetic energy or vice versa, as classified into PEW, AIW, EI-AIW, SL-EI-AIW, SB-EI-AIW, etc. according to the characteristics.

The copper conductor shall meet the requirements of copper wire in GB/T5584-2020, and the surface of copper wire shall be clean and smooth without burrs, scratches, oxide layer and oil stain.
Short Description:
Enameled Copper Wire is one kind of magnet wire which is consisted of bare round copper as the conductor and multi-layer insulation layers. The multi-layer insulation layers can be polyester, modified polyester or polyester-imide and so on.
Our Enameled Round Copper Wire is one kind of enameled wire which has high heat resistance. Its temperature class can be from 130ºC to 220ºC.
Copper is the standard used conductor material with excellent conductivity and very good windability. For special applications a wide variety of conductor materials is offered, alloys of copper for special characteristics like higher mechanical strength or bending performance.
