ECCA(Enameled Copper Clad Aluminum) Wire:Copper clad aluminum (CCA) wire is a bimetallic wire with a copper cladding concentrically covering an aluminum core, which combines the optimum properties of both metals in a single composite material ideally suited for most electrical conductor applications. The processing method of CCA wire is similar to that of copper wire during cable manufacture.Manufacture standard: SJ/T 11223-2000, ASTM B566:1993, Copper Clad Aluminum Wire The wire is divided into two mechanical status: Annealed (A) and Hard drawn (H), and the copper percentage in volume is 15%. Our product possess excellent  elongation rate of 13%.We specialize in bare CCA wire and Enameled CCA wire, the diameter of the wire ranging from 0.10mm - 0.80mm . Also can produce at your request.Advantages of CCA:1. Light-weight: CCAW is about one-third of the weight of copper wire of the same thickness. This is extremely advantageous for reducing the weight of the coil2. DC resistance: CC
