Copper rods with different zinc content will also have different colors, such as zinc content of 18%-20% will be reddish yellow, while the zinc content of 20%-30% will be brownish yellow.
Copper rods are more widely used than pure iron. Each year, 50% of copper is electrolytically purified into pure copper for use in the power industry. The copper mentioned here needs to be very pure indeed, containing more than 99.95% copper. Very small amounts of impurities, especially phosphorus, arsenic and aluminum, can greatly reduce the electrical conductivity of copper. Oxygen in copper (small amounts of which are easily mixed in copper smelting) has a significant effect on the conductivity of copper. Copper used in the electrical industry is generally oxygen-free copper.
