Supply Bare CCA wire, Spec. Dia. from 0.10mm-6.00mm, widely used in coaxial cable For the mass ratio of the copper, it is 40% in the copper clad aluminum(CCA) wire. That is to say there is about 400kg copper in 1ton copper clad aluminum(CCA) and its length is equal to the one of 2.5t pure copper. As a result, 1t copper clad aluminum wire can save 1.33t coppers.
