Features Copper Material: Enameled Wires are made of high electrical conductivity copper.Directly welding without scraping isolation layer. Repair Toool: Enameled Wires are used in professional maintenance of mobile phones, computers, laptops and other precision motherboard. Good alternative：A copper wire can take the place of the wire cable.Enameled wire is a copper wire coated with a very thin layer of insulation. Application tool：Enameled wires are used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire. Sufficient Length：Each enameled wire is about 12 meters long, which is enough for home or shop use. Description: Enameled wire is a copper wire coated with a very thin layer of insulation.
