Definition of Copper

Copper is a chemical element whose chemical symbol is Cu and whose atomic number is 29, and it is a transition metal. The most common use of copper is in the manufacture of electrical wires, which are usually made of pure copper because it is second only to silver in electrical and thermal conductivity, but is much cheaper than silver.

Types of copper

Many people think that there is only one type of copper, but in fact there are other different types of copper. For example, alloy copper: brass is an alloy composed of copper and zinc; white copper is an alloy of copper and nickel; bronze is an alloy formed by copper and elements other than zinc and nickel, mainly tin bronze, aluminum bronze, etc.; purple copper is a copper with a high copper content, and the total content of other impurities is less than 1%.

Types of copper can be classified by work material: copper sulfate, copper chloride, copper rods, copper rows, copper ingots, copper sheets, copper wires, copper alloys, rough copper, copper strips, copper oxide, copper foil, copper tubes, copper foil, copper clay, copper castings, electrolytic copper, other copper alloys copper materials.

Types of copper can be classified as pure copper or copper alloys made into various shapes, such as rods, wires, plates, strips, strips, tubes, foils, etc. collectively known as copper materials.

Types of copper can also be classified in various shapes made of pure copper or copper alloys, such as rods, wires, plates, strips, tubes, foils, etc. collectively known as copper materials.

Applications of copper

Electricity transportation

Highly conductive copper is consumed in large quantities for power transmission. This industry uses copper for power, wire and cable, bus bars, transformers, switches, plugging components and connectors.

In the manufacture of electric motors

In motor manufacturing, the application of copper is shown in the high conductivity and high strength copper alloy. The main copper parts used are the stater, rotor and shaft head, etc. In large motors, the winding's are cooled with water or hydrogen, called dual water interceded or hydrogen cooled motors, which require large lengths of hollow conductors.

Communication cables

Since the 1980s, fiber-optic cables have been replacing copper cables in communication trunk lines due to their advantages such as high current-carrying capacity, and their application is rapidly spreading. However, the conversion of electrical energy into optical energy and the input lines to users still require the use of large amounts of copper. With the development of communication business, people rely more and more on communication, the demand for both fiber optic cable and copper wire will continue to increase, so the application of copper is increasingly widespread.

In short, the application of copper in addition to the above, but also in the energy and petrochemical industry occupies an important position, even the transportation industry also has a place, aircraft, railroads, ships are inseparable from copper manufacturing.
