Copper Cathodes M1k

Copper Cathodes M1k

Copper is a soft, ductile, easily amenable to forging, rolling and other methods of plastic deformation, reddish - yellow metal. Its distinctive properties of high electrical and thermal conductivity.
According to its characteristics inferior to copper only silver, but the various impurities such as iron, aluminum, lead, bismuth, and so forth. Impair its electrical conductivity. For example, 0.02% of aluminum electric resistance increases by 10%. High purity copper with a content of impurities not more than 0.1% is obtained by electrolytic refining, which is the final product - copper cathodes. Standard 546 - 2001 defines the technical conditions of GOST 859 - 2001 chemical composition of copper cathodes. In accordance with the latter, depending on the presence of impurities, copper cathodes are the following brands: M00k, M0k, M1k and m2K.
Covered copper cathodes M1k contain the following, %:

 

  • ? 99,95
  • Copper Bismuth - 0,001
  • Tin - Nickel
  • 0.002 - 0.002
  • Iron - 0,003
  • Zinc - Arsenic
  • 0.003 - 0.002
  • Phosphorus - 0,002
  • Antimony - 0,002
  • Lead -
  • Silver 0.003 - 0.003
  • Sulfur - 0.004
  • Oxygen - 0,020 unique properties of copper dictate its scope. Basically, it's electrical. Copper cathodes used as the raw material for further manufacturing of wire tire rod, electrolytic copper powders. At the beginning of copper ingots are melted in the desired shape. Further, by rolling the final products obtained. Alloys based on copper, brass and bronze, resulting from application of various alloying elements have higher mechanical properties.
