0.40 - 0.8mm Ultra Fine Copper Magnet Wire 2UEW / 3UEW Enamelled Wire For Voice Coils

The wire itself is most often fully annealed, electrolytically refined copper. Aluminum magnet wire is sometimes used for large transformers and motors. However, because of its lower electrical conductivity, an aluminum wire must have 1.6 times the cross sectional area as a copper wire to achieve comparable DC resistance. Smaller diameter magnet wire usually has a round cross section. Thicker magnet wire is often square or rectangular (with rounded corners) to permit more efficient use of available winding space. Older insulation materials consisted of cotton, paper or silk and were useful for lower temperature applications (up to 105°C). Modern magnet wire typically uses one to three layers of polymer film insulation, often of two different compositions, to provide a tough, continious insulating layer.
