Another product which MWS produces is its line of high-performance film-coated plated wires.  These insulated wires were developed for applications where severe operating environments may degrade conventional conductor materials. Conventional copper wires are plated with gold, silver, or nickel in a variety of plating thicknesses, and then are film-insulated.  At elevated temperatures, these wires are capable of operating for extremely long periods of time, as the plated constructions prevent high-temperature chemical migration and conductor oxidation. Tin and copper plated wires are insulated for lower temperature applications. In addition to conductor protection, these plated constructions can improve a wire's solderability, conductivity, and overall strength. Film thicknesses can range from single to extra heavy special builds. See Magnet Wire Insulations for a complete list of insulations. Sizes 14-56 AWG can be produced in single end, parallel bonded, and twisted constructions.
