The electrical conductivity and thermal conductivity of red copper are second only to silver, and it is widely used in making electrical and thermal conductive equipment. Copper has good corrosion resistance in the atmosphere, seawater, certain non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solutions and various organic acids (acetic acid, citric acid) and is used in the chemical industry. In addition, red copper has good weldability and can be made into various semi-finished products and finished products through cold and hot plastic processing. In the 1970s, the output of red copper exceeded the total output of other types of copper alloys.

Red copper is a relatively pure type of copper. It can generally be considered as pure copper. It has good electrical conductivity and plasticity, but poor strength and hardness. Copper has excellent thermal conductivity, ductility and corrosion resistance. Trace impurities in copper have a serious impact on the electrical and thermal conductivity of copper. Among them, titanium, phosphorus, iron, silicon, etc. significantly reduce the electrical conductivity, while cadmium, zinc, etc. have little effect. The solid solubility of sulfur, selenium, tellurium, etc. in copper is very small, and they can form brittle compounds with copper, which have little effect on the conductivity, but can reduce the processing plasticity.

The copper plate has good mechanical properties, good plasticity in the hot state, acceptable plasticity in the cold state, good machinability, easy fiber welding and welding, and corrosion resistance. It is a common variety of red copper that is widely used.

Copper tube is a type of non-ferrous metal tube. Are pressed and drawn seamless tubes. Copper tubes are much more widely used than pure iron and are generally used in the electrical industry

Copper rods are named after their purple-red color. They have good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed. Generally used in chemical industry

Copper wire, that is, linear copper (red copper). Pure copper is rose red, and it turns purple after a copper oxide film is formed on the metal surface. Therefore, industrial pure copper is often called red copper or electrolytic copper. It is generally used to make wires, cables, brushes, etc.; it has good thermal conductivity and is often used to make products that must prevent magnetic interference. Magnetic instruments and meters, with excellent plasticity and easy hot and cold press processing
