Description

Copper Covered Aluminum Wire

By applying our patented clad-welding technique, the wire is made by fusing a core aluminum wire with external copper cladding. The two different kinds of metal are metallurgically bonded at the interface and the copper-cladding thinckness remains constant, so they become a single and indissociable wire.
