Solderable 2UEW/3UEW Super Thin Magnet Wire Enameled Copper Wire
In the audio industry, wires made from silver instead of copper are sometimes used. Various other insulators such as cotton (sometimes permeated with some kind of coagulating agent/thickener, such as beeswax) and polytetrafluoroethylene (Teflon) can be found. Older insulation materials include cotton, paper, or silk, but these are only useful for low-temperature applications up to 105°C.
For ease of manufacturing, some low-temperature-grade magnet wire has insulation that can be removed by the heat of soldering.This means that electrical connections at the ends can be made without stripping off the insulation first, disadvantage however is that it can melt accidentally. Laser wire stripping has the ability to remove sections of the wire insulation to improve connectivity; laser technology can provide unrivalled precision and repeatability to ensure precise connectivity.
