UL approved polyurethane coated round copper magnet wire is a metallic conductor insulated with a varnish and generally used for electrical applications. The Magnet Wire is also widely used round color aiw copper winding magnet wire.

ENAMELLED COPPER WIRE & ENAMELED ALUMINIUM WIRE is a fundamental part of a winding in every electrical machine or apparatus. 

What are the international standards for magnet wires?
International standards like IEC group magnet wires according to ranges of specific outer diameters. IEC groups the insulation in Grade 1, 2, or 3, NEMA in single, heavy, or triple, and JIS in class 0, 1, 2, or 3. The tolerances in these standards can be further restricted if necessary to design and optimize the wound coils and final products.

What is the raw material for copper wires?
For copper wires an 8 mm copper rod (5/16″ in USA) is used as raw material, which is drawn through drawing dies to the required bare wire dimension in several stages. The copper rod has to be of high purity and consistenly high quality to manufacture fine and ultrafine wires of sizes below 10 µm.

Temp. Class:130ºC
Availability:0.08~3.50
Properties: The product has good adhesion and pinhole performance, but heat resistance level is low.
Applications: Suitable for long-term working temperature for 130 :use in lower temperature level of ordinary industrial motors.
