Our leading bimetallic product is CCA wire.By applying patented clad-welding technique,the wire made by fusing a core aluminum or steel wire an external copper cladding.The two different kinds of metals are metallurgically bonded at their interface and the copper-cladding thickness remains constant during pulling and neat processing,and thus meets the line diameter and electronic characteristics as custmers' require.

Because of skin effect,the AC conductivity of CCA equals to solid copper when frequency greater than 5MHZ.
