Special Purity Of The Copper Bar
Copper rods are more widely used than pure iron. Every year, 50% of the copper is electrolytically purified into pure copper for use in the power industry. Very small amounts of impurities, especially phosphorus, arsenic, and aluminum, can greatly reduce copper's electrical conductivity. The oxygen in copper (a small amount of oxygen in copper smelting is easy to mix) has a great influence on the electrical conductivity of copper. The copper used in the electrical industry is generally oxygen-free copper.
