Guangdong Metal Corporation is a leading copper wire manufacturer and supplier.
Copper wire used in the electrical industry. The red copper mentioned here is indeed very pure, containing more than 99.95% of copper. A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Oxygen in copper (a small amount of oxygen is easily mixed during copper smelting) has a great influence 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 the copper crystals from joining together, causing thermal embrittlement and affecting the processing of pure copper. This kind of pure copper with high purity is generally refined by electrolytic method: impure copper is used as anode, pure copper is used as cathode, and copper sulfate solution is used as electrolyte. When the current passes, the impure copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. Copper refined in this way; purity up to 99.99%.
Copper is a kind of relatively pure copper. It can be generally regarded as pure copper. Its conductivity and plasticity are better, but its strength and hardness are worse.
Purple copper is also used in furniture and decoration such as doors, windows and armrests.
1. Pure copper has good conductivity and is widely used in the manufacture of wires, cables, brushes, etc .;
2. Good thermal conductivity, commonly used to manufacture magnetic instruments and meters that need to prevent magnetic interference, such as compasses, aviation instruments, etc .;
3. Excellent plasticity, easy to hot and cold pressure processing, can be made into pipes, rods, wires, strips, strips, plates, foils and other copper materials.
