High quality Copper wire strand
Product Introduction:
The high quality of copper wire strand 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.
Product Characteristics:
1. Adopting Φ8mm high-quality oxygen-free copper wire ingots as raw material.
2. Using equal diameter wheel to pulling and pushing to ganrantee low loss of the wire material.
3. Adopting the micrometer slide pulling process, and the outgoing-line block is spinning block, which improves the circle performance of high quality copper wire strand.
4. The take-up tension can be automatically regulated, and the Annealing voltage follow the line-pulling speed automatically which lead uniform annealing.
5. Good surface finish of wire material, good flexibility and ductility, and the elongation is greater than 35%.
6. Convenience in transportation, easy line-setting process, used for the high speed production of double-zero lacquer covered flat wire.
