swg copper magnet wire is one of insulated copper wire is a metallic conductor insulated with a varnish and generally used for electrical applications.

Can aluminum be used as a conductor material for magnet wire?
For low weight and larger diameters Aluminum sometimes can be used as a conductor material for magnet wire. Because of the difficult contacting of Aluminum wire with problems of oxidation Copper Clad Aluminum can help to compromise between Copper and Aluminum.

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.
