Oxygen-Free Copper
Many cables today are advertised as using "oxygen-free copper," copper which has been annealed in an oxygen-free atmosphere. OFC is popular in audio cables, and has begun to make inroads into the video cable market as well, Oxygen free copper strip widely used in domestic andindustrial sectors automatic lathes and CNC lathes has producedeco-environmental protection and health safety requirements, such aselectronics, telecommunications, connector, connectors, hardware and otherengineering components.

 

Oxygen-Free Copper is produced by the direct conversion of selected refined cathodes and castings under carefully controlled conditions to prevent any contamination of the pure oxygen-free metal during processing. The method of producing OFC Copper insures extra high grade of metal with a copper content of 99.99%. With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree. Characteristics are high ductility, high electrical and thermal conductivity, high impact strength, good creep resistance, ease of welding, and low volatility under high vacuum.
