Copper is a non-ferrous metal closely related to human beings. It is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in China.
1. One of the five application fields of T2, red copper row and red copper tube: copper is the most widely used and largest in the electrical and electronic industry, accounting for more than half of the total consumption. For all kinds of cables and wires, motors and transformers, switches and printed circuit boards; In machinery and transport vehicle manufacturing, used for manufacturing industrial valves and accessories, meters, sliding bearings, molds, heat exchangers and pumps, etc.
2, purple copper plate T2, red copper row, red copper tube two of the five applications: copper in the chemical industry is widely used in the manufacture of vacuum, distilling pot, brewing pot, etc..
3, purple copper plate, copper row, three of the five fields of application: copper in the national defense industry to manufacture, gun parts, etc., every production of 3 million hair, need 13-14 tons of copper.
Four of the five application fields of purple copper plate, red copper row and red copper pipe: copper in the construction industry, used for all kinds of pipes, pipe fittings, decorative devices, etc.
5, purple copper plate, red copper row, red copper tube five applications of the five fields of five: copper in medical use, in the 1970s, Chinese medical inventor Liu Tongqing, Liu Tongle research found that the copper element has a strong function, and successfully developed the corresponding "cancer 7851", in the face of success. Later, Mexican scientists also discovered that copper had a function. Recently, British researchers found that copper element has a strong antiseptic effect. It is believed that in the near future, copper will make a great contribution to the improvement of human health.
Purple copper plate sometimes also participate in a few deoxidation elements or other elements to improve the raw material and function, so also classified as copper alloy. Copper strip has excellent corrosion resistance in air, sea water and some non-oxidizing acid, alkali, salt solution and a variety of organic acids (acetic acid, citric acid), used in chemical industry. In addition, purple copper plate has excellent weldability, can be made into a variety of semi-products and products by cold and thermoplastic processing. In the 1970s, the output value of purple copper plate exceeded the total output value of other kinds of copper alloys.
The tensile strength, elongation and Brinell hardness of annealed copper sheet are 22 ~ 25 kg/mm 2, 45 ~ 50% and 35 ~ 45 respectively at room temperature. It has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. Mainly used for manufacturing generators, busbars, cables, switchgear, transformers and other electrical components and heat conduction devices such as heat exchangers, pipes, solar heating equipment flat collector. Commonly used copper alloys are divided into brass, bronze and white copper.
Pure purple copper plate is purple red metal, commonly known as "purple copper plate", "red copper plate" or "red copper plate". Purple copper plate has ductility. Pure copper, the size of a drop of water, can be pulled into filaments up to two kilometres long or calendered into bright foil larger than a bed. The most valuable property of copper row is its very good electrical conductivity, second only to silver among the common metals. But copper is so much cheaper than silver that it has become the hero of the electrical industry.
