The use of copper rods is much broader than that of pure iron. Every year, 50% of copper is electrolytically purified to pure copper for use in the electrical industry. The copper mentioned here is indeed very pure, containing more than 99.95% of copper. A very small amount of impurities, especially phosphorus, arsenic and aluminum, will greatly reduce the electrical conductivity of copper. Oxygen in copper (it is easy to mix in small amounts of oxygen when smelting copper) has a great influence on the electrical conductivity. Copper used in the electrical industry must generally be oxygen-free copper. In addition, impurities such as lead, antimony, bismuth and the like can make copper crystals not bond together, resulting in hot brittleness and also affecting the processing of pure copper. This pure copper with high purity is generally refined by electrolysis: impure copper (ie, blister copper) is used as the anode, pure copper is used as the cathode, and copper sulfate solution is used as the electrolyte. When the current passes, the impure copper on the anode gradually melts and pure copper gradually precipitates on the cathode. This refined copper; purity of up to 99.99%.
Copper is a kind of relatively pure copper, generally can be approximated as pure copper, conductive and plastic are better, but the strength and hardness are worse.
