There are mainly two types of round enameled wire: copper and aluminum. The enameled aluminum round wire is mainly used as a conductor for the movement of the coil. Its diameter ranges from 0.20mm to 8.0mm (SWG1-36, AWG1-32). It has different insulation layers, such as polyurethane. Polyester, polyesterimide, polyimide, etc.. Enameled round aluminum wire meets production standards: IEC60317, NEMA MW1000 / JIS C3202.
