copper clad aluminium , CCA,

copper clad aluminum, aluminum magnesium alloy wire are the bimetallic composite wire with the advantages of easy & reliable connection, light weight, around good, economic and other benefits, safe & reliable as well as the pure copper.

 Through the practices of the industry, they insist that the wire and cable industry use the CCAM & CCA wire are also a good way to ease the current pressure for enterprises. The ccam, cca conductive properties, various parameters & indications are the same with the equivalent cross-section of copper wire, the density is small than copper, only 30-35% of pure copper wire, overcome the aluminum conductor defects about large contact resistance, low intensity, easy to creep, easy corrosion & oxidation. They are the ideal branch line for RF coaxial cable, communication materials, CATV cable, control cable, power cable, Twisted-pair, cloth wire, data cable, network line, audio cable etc.     

The cca & ccam divided into two kinds for state: annealing one is expressed by A; 2 non-annealing one expressed by H.  As per the copper layer volume percentages be classified 10% & 15%, the 10% cca or ccam is usually used in the transmission of Low-frequency current. and the 15% widely for high-frequency current transmission.
