copper strand wire

Product Introduction: the high quality oxygen-free copper wire produced by our company adopts imported CATH-1 series of electrolytic copper in high purity, whose copper content is higher than 99.996%. We apply the upward-pulling technology in the protection of inert gas, and ensure the oxygen content of copper bar is lower than 8ppm. Through the hot-working process in vacuum, the oxygen-free copper bar becomes more uniform and dense in structure, and better in its inner quality. Through continuous pulling and pushing process to the 3mm copper bar by equal diameter wheel, the flexibility and circle performance are ganranteed, which enables us to supply high quality ingots for the next-process customers.
