Description:

copper wire, that is, linear copper (red copper). Pure copper is rose-red, copper oxide film formed on the metal surface is purple, so industrial pure copper is often called red copper or electrolytic copper.

Characteristics:

 low voltage loss: due to low resistivity of copper core wire, low voltage drop of copper core wire under the same current flow in the same section. Oxidation resistance, corrosion resistance: the connection head of copper core wire is stable and will not be caused by oxidation. The instability of the joint of aluminum wire is often increased by oxidation. There is an accident. Therefore, the accident rate is much larger than the copper core wire. The energy consumption is low: because of the low resistivity of copper, it is obvious that the electrical energy loss of copper wires is lower than that of aluminum wires. This is very obvious. This is helpful to improve the utilization of electricity and protect the environment.

Usage:

copper is used more widely than pure iron. 50% copper is electrolyzed to pure copper every year for electrical industry. The copper in question really needs to be very pure and contains more than 99.95% copper. A very small amount of impurities, especially phosphorus, arsenic, aluminum and so on, will greatly reduce the conductivity of copper. Oxygen in copper (which is easy to be mixed with a small amount of oxygen in copper smelting) has a great influence on conductivity. Copper used in electrical industry must be oxygen free copper. In addition, lead, antimony, bismuth and other impurities will make copper crystal can not be combined, resulting in hot brittle, will also affect the processing of pure copper. This kind of pure copper with high purity is usually refined by electrolysis: using pure copper as anode, pure copper as cathode and copper sulfate solution as electrolyte. When the current passes, the impure copper on the anode gradually melts and the pure copper is precipitated on the cathode. Copper so refined; purity up to 99.99. Red copper is a kind of copper which is relatively pure, which can be considered as pure copper. Its electrical conductivity and plasticity are better, but its strength and hardness are worse. Copper is also used in doors, windows, handrails and other furniture and decoration.
