We are a leading manufacturer of Copper-clad Steel Wire (CCS) and Copper-clad Aluminum-Magnesium Alloy Wire (CCAM) in China. CCS and CCAM have widely used in Video/Audio cable, coaxial cable, microphone cable etc. (0.10mm--5.0mm) As you know, copper has good conductivity and high strength, steel has low resistance, aluminum is easy to be processed since its low density. The wire of CCS has the high strength and low resistance, both of the features of steel and copper. The extensibility is more than 6%. The wire of CCAM has both of copper and aluminum features. To be candid with you, from the use of CCS and CCAM, the cost will be saved much. In addition, the copper-layer of CCA and CCAM is uniform in density, good in consistency and extensibility. We feel confident you will satisfy with our products in operation.
