Purity: Copper cathodes are at least 99.95% pure. 
Dimensions: Copper cathodes can vary in size, but are typically around 914 mm x 914 mm x 12 mm. 
Weight: Copper cathodes can weigh around 125 kg per sheet. 
Electrical resistivity: Copper cathodes are tested for electrical resistivity using Test Method B 193. 
Composition: Copper cathodes contain trace amounts of other elements, such as bismuth, tellurium, silver, and selenium. 
Copper cathodes are produced from copper ore through smelting and electrorefining to remove impurities. They are the primary raw material for copper rods used in the wire and cable industry. Copper is also used in the production of brass, copper tubes, and copper sheets.
