[0002] Due to different copper rod production processes, the oxygen content and appearance of each rod vary. The copper rod produced above has an oxygen content below 20 ppm and is called oxygen-free copper rod. Deoxidized aluminum rod is an aluminum alloy rod made by removing oxygen from molten aluminum by adding certain elements such as titanium and aluminum. Its primary components are aluminum and titanium, with smaller amounts of iron, silicon, and manganese. Deoxidized aluminum rod is highly pure, exhibits excellent conductivity, and is easy to work with, making it widely used in modern industry. The finished oxygen-free copper and aluminum rods are coiled, stacked, and placed on pallets. Workers then manually wrap the coils to prevent damage during transportation.
