High purity oxygen free copper wire core refers to copper wire core that is free of impurities and has extremely high purity, usually used for manufacturing products such as wires and cables. This type of wire core has the characteristics of high purity, low resistivity, good conductivity, high strength, and long service life.

In the manufacturing process of oxygen free copper wire cores, special smelting processes and equipment are required to remove impurities and oxygen elements from copper. Common smelting processes include vacuum melting, horizontal continuous casting, extrusion processing, etc. Among them, vacuum melting can effectively remove oxygen elements from copper, horizontal continuous casting can produce large diameter oxygen free copper rods, and extrusion processing can process oxygen free copper rods into wire cores of different specifications.

The purity of high-purity oxygen free copper wire cores is usually above 99.99% and does not contain any impurity elements. This high-purity oxygen free copper wire core has excellent conductivity and mechanical properties, and is widely used in the manufacturing of power cables, communication cables, electronic devices and other products.

It should be noted that the oxygen free copper wire core does not contain any impurities, but contains a very small amount of impurity elements. If higher purity copper wire cores are required, stricter smelting and processing processes are required.
