The main characteristics of a high conductivity copper, and thermal conductivity. The higher the content of Cu in the metal, the higher the degree of electrical conduction, so pure copper valued more than the low-purity copper. A cathode manufactured using copper electrolytic refining according to GOST 546-2001 and used for the production of cast, wrought products, as well as alloys. Most often used in copper cathode production of wire, sheets, tapes and strips. The processing of Cu occurs in specialized smelters where copper is melted and poured in the form of ingots. Then, the ingots are subjected rental to further create the necessary products. Also, using a copper cathode obtained alloys to which is added a certain number of alloying elements.
Cathode copper must comply with a certain brand of metal; they are specified in ISO 859-2001. The chemical composition are the following brands of copper cathode: M00k, M0k, M1k, m2K. These marks differ in the level of the metal content of copper, oxygen, phosphorus and other impurities. On the level of data items dependent properties of the metal itself and cathodes application in industry. Most copper content in the metal has a stamp M00k - 99.8%, the oxygen content - 0.1% phosphorus - 0%. Brand m2K has a low content of Cu - 99,93%, O - 0,03%, P - 0,002%. Thus, it is seen from the percentage chemical composition of metal elements in the copper m2K cathode has a lower degree of electrical and thermal conductivity compared with M00k, M0k, M1k. However, m2K grade metal production is less expensive, so manufacturing cost of the specified mark is lower than when using copper cathodes with a high copper content. M2K is used for cable production, electrolytic copper powder, tires for cars, and also for the manufacture of pipes. In addition, due to friction and resistance to corrosion of the copper cathode production goes on and solder alloys, which are used in mechanical engineering.
