and human health

Copper ions (copper) are essential elements for living things, whether animals or plants. Copper deficiency in the human body can cause anemia.

Hair abnormalities, bone and arterial abnormalities, and even brain disorders. However, if it is excessive, it will cause cirrhosis.

Diarrhoea, vomiting, movement disturbances, and sensory neurological disturbances. In general, beef, sunflower seeds.

Cocoa, black pepper, lamb liver, etc. are rich in copper.

Copper is an essential trace mineral that enters the bloodstream 15 minutes after ingestion and is also present in red blood cells.

Inside, and outside can help ferrotransmitter proteins in heme.

It plays an important role in the formation of catalysis. Moreover, copper is not easily destroyed during food cooking.

In ancient times, it was mainly used for utensils, artworks and casting, and the more famous utensils and artworks such as Simu Wuding and Siyang Fangzun.

Hyundai is widely used in electrical, light industry, machinery manufacturing, construction industry, defense industry and other fields.

Common alloys: Copper can be used to make a variety of alloys.

1) Brass. Brass is an alloy of copper and zinc, named for its yellow color. Brass has good mechanical properties and wear resistance, and can be used to make precision instruments, ship parts, gun shells, etc.

Brass sounds good when struck, so musical instruments such as gongs, cymbals, bells, and trumpets are made of brass.

2) Nautical brass.

The alloy of copper, zinc and tin is resistant to seawater erosion and can be used to make ship parts and balancers.

3) Bronze. The alloy of copper and tin is called bronze, which is named because of its blue color. Bronze generally has good corrosion resistance, wear resistance, castability and excellent mechanical properties.

It is used in the manufacture of precision bearings, high-pressure bearings, seawater corrosion-resistant mechanical parts on ships, as well as various plates, tubes, bars, etc. Bronze also has an unusual property - "heat shrinkage and cold expansion", which is used to cast statues, and when cooled, it expands to make the eyebrows clearer.

4) Phosphor bronze.

An alloy of copper, tin and phosphorus, which is hard and can be used to make springs.

5) Cupronickel. Cupronickel is an alloy of copper and nickel, and its color is the same as silver. It is commonly used in the manufacture of coins, electrical appliances, meters, and ornaments.

6) Eighteen karat gold (18k gold or rose gold).

6 24 copper and 18 24 gold alloy. Reddish yellow, hard, can be used to make jewelry, ornaments.

The main uses of copper are as follows.

1. Power transmission.

A large amount of highly conductive copper is consumed in power transmission, which is mainly used for power cables, busbars, transformers, switches, plug-in components and couplings.

2. Motor manufacturing.

In the manufacture of electric motors, copper alloys with high conductivity and high strength are widely used. The main copper parts are stator, rotor and shaft head.

3. Communication cables.

Since the 80s, due to the advantages of large current-carrying capacity of optical fiber cables, copper cables have been continuously replaced on communication trunk lines, and have been rapidly popularized and applied. However, converting electrical energy into light energy and feeding the user's wiring still requires a lot of copper. With the development of the communication industry, people's dependence on communication is increasing, and the demand for optical fiber cables and copper wires will continue to increase.

4. Residential electrical circuits.

5. Electric vacuum device.

Electric vacuum devices are mainly high-frequency and ultra-high-frequency transmitters, waveguides, magnetrons, etc., which require high-purity oxygen-free copper and diffusion-strengthened oxygen-free copper.

6. Printed circuits.

Copper printed circuit is to use copper foil as a surface and paste it on a plastic plate as a support; Use the method of photography to print the circuit wiring diagram on the copper plate; Excess parts are removed by etching, leaving interconnected circuits.

Then, punch holes in the connection between the printed circuit board and the outside, insert the terminals of the joints or other parts of the discrete components, and weld them to this port, so that the complete circuit is assembled.

8. a lead frame.

Copper alloy is cheap, has high strength, electrical conductivity and thermal conductivity, excellent processing performance, needle welding and corrosion resistance, and can control its performance in a wide range through alloying energy, which can better meet the performance requirements of the lead frame, and has become an important material for the lead frame. It is currently the most used material in microelectronic devices.

9. Energy industry.

Many copper tubes are also used to utilize solar energy. For example, a swimming pool in a hotel near London, England, is equipped with a solar heater that keeps the water temperature at 18-24 in the summer. The solar heater contains 784 pounds (356 kg) of copper pipes.

10. Petrochemical industry.

Copper and many copper alloys have good corrosion resistance in aqueous solutions, non-oxidizing acids such as hydrochloric acid, organic acids (such as: acetic acid, citric acid, fatty acids, lactic acid, oxalic acid, etc.), various alkalis other than ammonia and non-oxidizing organic compounds (such as oils, phenols, alcohols, etc.); Therefore, it is widely used in the petrochemical industry to manufacture various containers, piping systems, filters, pumps and valves that come into contact with corrosive media.

It also uses its thermal conductivity to manufacture various evaporators, heat exchangers, and condensers. Due to the good plasticity of copper, it is especially suitable for the manufacture of heat exchangers with intricate structures and cross-braided copper tubes in modern chemical industry. In addition, bronze production tools are used in petroleum refineries; The original is that no sparks burst out during impact, which can prevent fire.

Copper can be used to make electrical wires, and because copper is second only to silver in electrical and thermal conductivity, but much cheaper than silver, the wires used are usually made of pure copper. Copper is easy to process and can be made into automotive parts and electronic parts by changing its shape through melting, casting, and calendering. These processed copper products are collectively referred to as copper elongation products.

Whereas, copper can be used to make a variety of alloys.

Copper is a metallic element and a transition element, the chemical symbol Cu, English copper, atomic number 29. Pure copper is a soft metal, the surface is reddish-orange with metallic luster when it is first cut, and the elemental color is purple-red. Good ductility, high thermal and electrical conductivity, so it is the most commonly used material in cables and electrical and electronic components, and can also be used as a building material, which can form many alloys.

Copper alloys have excellent mechanical properties and very low resistivity, the most important of which are bronze and brass. In addition, copper is also a durable metal that can be used many times without compromising its mechanical properties.

Copper was one of the first metals used by humans. As early as prehistoric times, people began to mine open-pit copper and use the obtained copper to make **, tools and other utensils, and the use of copper had a profound impact on the progress of early human civilization. Copper is a metal found in the earth's crust and oceans.
