Electrolysis can be used to produce ultra-pure copper (more than 99.95 percent purity), referred to as electrolytic copper. High purity is required because the vast majority of copper is utilized in the manufacture of electrical equipment, and even trace levels of copper impurity metals can significantly impact the metal's capacity to conduct electricity. Even a 0.05 percent concentration of arsenic impurity, for instance, will diminish the conductivity of the metal by 15%. Consequently, high-purity copper wires must be used to construct electric wires, especially when electricity is to be transported over long distances via high-voltage transmission lines. In addition, our organization sells electrolytic copper at a cheap price because of the high quality that has been maintained.
