Copper Wire
Products
With the technical cooperation with GE Company of the USA and Showa electric Company of Japan, we adopted the pollution free “Dip Forming” process to make Oxygen-Free Copper Rod.
There is no problem of pollution and no dust. It does not require picking, with 102% conductivity. Our copper rods are the best raw materials available for Wire and Cable Industry.

Oxygen-Free Copper Rod Manufacturing Process
Oxygen-Free Copper Wire
Oxygen Free Copper Rod is manufactured in continuous DIP FORMING PROCESS from electrolytic copper plate. The whole process that includes DIPPING, FORMING and HOT ROLLING are taken in reductive atmosphere without oxygen and hydrogen (oxygen content under 15PPM). The high purity copper rod and wire have those characteristics below, which are suitable for the high conductivity power cable, telecom cable, fine magnet wire and electronic wire.
Features
1、The Manufacture Process and Characteristics of Oxygen Free Copper Rod
Our Oxygen Free Copper Rod is manufactured in continuous DIP FORMING PROCESS from electrolytic copper plate. The whole process that includes DIPPING, FORMING and HOT ROLLING are taken in reductive atmosphere without oxygen and hydrogen. The high purity copper rod and wire have those characteristics below, which are suitable for the high conductivity power cable, telecom cable, fine magnet wire and electronic wire.
(1) Oxygen content is less than 15PPM, the average conductivity is 101%, higher than the other processes wire
(2) The particle grain is fine and excellent in twisting and drawing
(3) Less impurity, scrap and spur easy for fine wire drawing without break
(4) Smooth and bright surface, good adhesion in tin plating and enamel coating (Especially for rectangular wire)
(5) Extra low oxygen content, will not be brittle that caused by hydrogen
(6) Continuous process, the weight of each coil can be assigned by customer (Max 4 Tons)
