The enameled copper-clad aluminum wire has a composite conduction made of aluminum or aluminum alloy clad with copper. It possesses lightness in weight as aluminum as well as solderability and corrosion resistance of copper. Features Helps reduce the weight of coils made. The ratio of copper cladding can be selected among 10, 15% or the like. The copper cladding gives the wire the same degree of solderability as that of copper. Applicable standards : JCS 340 "Copper-clad aluminum wires", TOTOKU Standard Applications : VCM coils, optical pickup coils, voice coils.
