Copper cathode

Copper cathode - copper purified from impurities (bismuth, antimony, arsenic, iron, phosphorus, silver). It is supplied in the form of cathode sheets or semi-finished products - ingots, which are then processed by rolling. Copper cathodes are intended for the production of wire, tires, copper rod, copper electrolytic powders.
Copper cathode is obtained by electrolytic refining; it is practically pure, and therefore suitable for solving many technical problems. Copper received its name “cathode” during the electrolysis process, when it is deposited on the cathode.
Copper cathode is most often used for smelting into wire. This process is carried out in special smelting furnaces where various copper products are melted down into different ingot shapes that are optimally suited for rolling. In addition, alloyed copper alloys are produced using cathode copper; for this, copper sheets are cut and melted, adding the required amount of alloying elements.
