In cable manufacturing, copper conductors are widely used due to their excellent conductivity and stable mechanical properties. In order to further improve the overall performance of cables, more and more manufacturers are beginning to choose 99.99% oxygen-free copper (OFC) as conductor material.

Benefits of choosing oxygen-free copper for copper extension: Improved cable performance and long-term stability

February 19, 2025

Share:

1. Improve the conductivity of cables

Oxygen-free copper has a purity of up to 99.99% and contains almost no impurities. This means that its conductivity is much higher than that of ordinary copper, and it can transmit current more efficiently and reduce energy loss. For high-end cables that require efficient power transmission, oxygen-free copper is an ideal choice.

2. Enhance oxidation resistance and corrosion resistance

Oxygen-free copper uses special processing technology to avoid contact with oxygen, so it has stronger oxidation resistance. Ordinary copper is easy to oxidize, resulting in a decrease in conductivity, while oxygen-free copper can maintain good conductivity in various environments, ensuring long-term stable operation of the cable.

3. Superior mechanical properties and ductility

Due to the more uniform lattice structure of oxygen-free copper, it has better ductility and toughness. The cable can be stretched and bent more easily during the manufacturing process, and it is not easy to break, which is suitable for applications that require complex shapes and high reliability.

4. Extend the service life of the cable

Oxygen-free copper has a lower oxidation rate, which can effectively avoid the increase of contact resistance of the cable in long-term use and reduce the failure rate. Therefore, cables using oxygen-free copper have a longer service life and are particularly suitable for demanding power systems and communication networks.

5. Suitable for high-end applications

Although the cost of oxygen-free copper is slightly higher than that of ordinary copper, its superior performance makes it the preferred material for high-end power systems, precision electronic products, aerospace equipment and other fields. Choosing oxygen-free copper can ensure the stability and safety of cables in harsh working environments.

Summary

By choosing 99.99% oxygen-free copper as a conductor, you can significantly improve the cable's conductive efficiency, oxidation resistance and mechanical strength, reduce energy loss and extend the cable's service life. For industries with high requirements for cable performance, oxygen-free copper is undoubtedly the best choice.
