| Cathodes |
|
| The cathode is the basis product of copper for high grade applications. Pure copper is extracted in the form of cathodes during the electrolytic refining process from crude copper. |

Copper cathodes with certain contents of impurities are also registered and traded at the London Metal Exchange and the Comex. Qualitatively highgrade copper is characterised by the lowest contents of impurities, since even the smallest amounts in the ppm area of selenium, bismuth or
antimony significantly impact the conductivity.
NA copper, brand "NAESN" and "HK", is characterised by its high purity and consistent quality, regardless of the raw materials used. NAESN cathodes form the basis for the highgrade NA copper products.
