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.
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.
