Oxygen Free Copper

What is Oxygen Free Copper?​

Oxygen Free Copper C101 is extremely pure copper with very little oxygen content. With a typical oxygen content of less than 0.0005% and a typical copper grade of 99.99%, C101 Copper Without Oxygen is the highest-grade copper available, and the material properties closely resemble that of elemental copper. The target purity is so high that silver is removed as an impurity.

As an ultra-high purity copper product, C101 Copper Without Oxygen has very good electrical and thermal conductivity, has good machinability, and is highly ductile. By reducing the oxygen content to less than 0.0005% these properties are more exaggerated than standard copper products and as such find a variety of highly specialised industrial applications.

What is Oxygen Free Copper used for?​

  1. The higher the purity of any copper product, the better the corrosion resistance, the higher the electrical conductivity, and less heat is produced while conducting electricity. As the purest copper product possible, C101 Copper Without Oxygen provides the best results of any copper products.
  2. By removing almost all impurities there are very few interruptions to the metallic structure of the copper, and by removing almost all oxygen there is a significant reduction in oxidation of the metallic copper which can further impede performance.
  3. Due to the higher price that comes with the higher purity product, almost all uses of C101 Copper Without Oxygen are highly specialized. These include:
  4. Superior Audio/Visual Applications – high end audio/visual applications where quality is paramount will utilise copper wiring made from C101 Copper Without Oxygen.
  5. Large industrial transformers – the increased electrical conductivity of C101 Copper Without Oxygen can reduce the diameter of the wiring withing transformers and therefore reduce the amount of copper and the size of the overall installation.
  6. Long life applications – In large or very difficult to replace projects, the longer lifespan of C101 Oxygen Free Copper products can be beneficial.
  7. High vacuum applications – Any scientific requirement to minimize the presence of impurities in a vacuum environment can utilise C101 Copper Without Oxygen to ensure no contamination happens from the copper wiring.
  8. Often more than one of the above applications are found in an installation of C101 Copper Without Oxygen, such as in the largest particle accelerator in the world, the Large Hadron Collider.

How is oxygen free copper made?​

The processing of C101 Copper Without Oxygen is only different in the final refining stage. The standard high-purity copper is refined under standard atmospheric conditions to further reduce the oxygen content. The final refining process must be carried out in an oxygen free environment.

This can include pouring molten copper into the mold in an oxygen free environment, such as a vacuum or a carefully controlled inert atmosphere. C101 Copper Without Oxygen is the most expensive copper grade on the market due to the additional processing complexity of producing the required product purity.

Oxygen Free Copper

What is the difference between oxygen free copper and pure copper?​

  • Copper Without Oxygen: oxygen free copper is made of high-purity cathode copper. The solution is covered with calcined charcoal. The oxygen content produced by smelting and forging under closed conditions is very low. Copper without oxygen has high conductivity, good processing and welding properties, corrosion resistance and low temperature performance. Copper without oxygen is mostly used in audio equipment, vacuum electronic devices, cables and other electrical and electronic applications.
  • Pure copper: copper with high copper content. Generally, pure copper is oxygen-containing copper with a mass concentration of not less than 99.7% and very little impurity quality. Its appearance is dark purple, so it is also called red copper. Pure copper has good conductivity and thermal conductivity, excellent corrosion resistance and excellent weldability. Pure copper is widely used in making conductive and heat conducting equipment; It can be made into semi-finished products and finished products through cold and thermoplastic processing; Used in chemical industry.
