The use of copper is much more extensive than that of pure iron. Every year, 50% of copper is electrolytically purified into pure copper for use in the electrical industry. The copper mentioned here must be very pure, with a copper content of 99.95% or more. A small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. The oxygen content in copper (a small amount of oxygen is easily mixed in during copper smelting) has a great impact on the conductivity. Copper used in the electrical industry must generally be oxygen-free copper. In addition, impurities such as lead, antimony, and bismuth will prevent copper crystals from combining together, causing hot brittleness, and will also affect the processing of pure copper.<\/p>\n

This kind of high-purity pure copper is generally refined by electrolysis: impure copper (i.e. crude 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 through, the impure copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. The copper refined in this way can reach a purity of 99.99%. Red copper is a relatively pure type of copper, which can generally be considered as pure copper. It has good conductivity and plasticity, but poor strength and hardness.<\/p>","protected":false},"excerpt":{"rendered":"
