What are the general uses of copper?
Copper is one of the oldest metals used by man. Archaeological evidence shows that as early as 10,000 years ago, people in Western Asia used copper to make objects such as decorations. Archeology has also discovered that as early as around 3000 BC, bronze alloys made of copper and tin brought humanity into the Bronze Age.
What are the general uses of copper? Copper is malleable, corrosion resistant, durable and an excellent conductor of electricity and heat; alloys made of copper and other metals such as zinc, aluminum, tin, nickel, etc. have new properties and many special uses. Today, copper is widely used in homes, industries, high technology and other occasions. Copper is also one of the metalsto the most renewable. Currently, recycled copper represents approximately 40% of the world's total copper supply.
What are the general uses of copper? Copper is used in various devices and appliances to conduct electricity and heat, as well as in communications, water and gas transportation, and roof construction. Copper also acts as a fungicide to protect plants and crops. Copper alloys, like bronze, are used in making works of art such as statues. Copper is widely used in electrical systems. Its strength, ductility and corrosion resistance make it an excellent conductor for building circuits. It is also used as a power cable for high, medium and low voltages and is a material for making electric motors. and transformers. The International Copper Research Group pointed out that although optical fiber has replaced copper in some communications systems, copper remains the preferred material in the "last mile" or section. In personal computers and hardware, copper cables are widely used. In the construction of roofs, it is interesting to use copper in order to resist extreme climatic conditions. Copper exposed to this climatic environment develops a patina (basic copper carbonate) on its surface, characteristic of this application of copper.
Copper and brass are widely used in water piping systems to make the system more resistant to bacteria.
Copper is mainly used in transportation equipment, such as ships, cars and airplanes. The copper-nickel alloy used in the hull prevents the formation of biofouling and reduces drag. According to the International Copper Research Group, the average copper content per car is 27.6 kg and the copper content per largest airliner is 4,000 kg. The thermal conductivity, strength and corrosion resistance of copper allow it to be used as a car radiator.
In machine manufacturing, copper alloys are used to make gears, bearings and turbine blades. Copper is used, among other things, in pressure vessels and large tanks. Copper alloys are resistant to salt corrosion, making them advantageous for use in the maritime industry, including coastal equipment, seaside power plants and desalination equipment. Copper also exists in the human body, as well as animals and plants, and is essential for maintaining human health.
What precious metals are found in thermal power plants ?
There is copper in the generating machine of agricultural tricycles
It is used in all engines. It's copper because copper conducts electricity better than brass.
Generators refer to mechanical equipment that converts other forms of energy into electrical energy. They include water turbines, steam turbines and diesel generators. Driven by an oil engine or other electrical machine, the energy generated by water flow, air flow, fuel combustion or nuclear fission is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy by the generator.
Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. There are many forms of generators, but their operating principles are all based onhe law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the conversion goal of energy.
Do you want to ask: “Which power plant equipment contains precious metals?” Common equipment containing precious metals in power plants includes: generators, lubricating oil systems, isolation switches, flue gas denitration devices, and fins. tubes.
1. Generator: The generator rotor is usually made of copper-clad steel, of which copper is an important precious metal.
2. Lubricating oil system: The lubricating oil systemin power plants usually uses silver-containing lubricating oil, such as silver foil lubricating oil.
3. Isolation Switch: Isolation switch contacts are usually made of copper containing silver.
4. Flue gas denitrification device: The flue gas denitrification device generally uses a vanadium-containing catalyst to reduce nitrogen oxides present in the exhaust gas, of which vanadium is a precious metal.
5. Finned Tubes: Finned tubes are usually made of aluminum.
