The uses of metallic gold in life, what are the metals in life

Each time it is not determined by the monetary commodity attribute of **. Due to the excellent characteristics of the currency, it has historically served as a monetary function, such as a measure of value, a means of circulation, a means of storage, a means of payment and a world currency. At present, many countries, including major Western countries, still occupy a very important position in their international reserves.

2. It is used as a jewelry decoration. Gorgeous ** jewelry is a symbol of a person's social status and wealth.

3. Application in industry and science and technology. **It has extremely high stability against corrosion, good electrical and thermal conductivity. The nucleus of gold has a large effective cross-section for capturing neutrons; The reflective ability to infrared rays is close to 100; It has various catalyst properties in alloys of gold; Gold also has good manufacturability, and is easy to process into ultra-thin gold foil, micron gold wire and gold powder; Gold is easily plated on the surface of other metals and pottery and glass, and gold is easily welded and forged under a certain pressure; Gold can be made into superconductors and organic gold, etc.

It is precisely because gold has so many beneficial properties that it is widely used in modern high-tech industries, such as electronic technology, communication technology, aerospace technology, and chemical technology.

Let me briefly talk about the common metals in life, some of which are not often seen, or cannot be seen in essence, because most of the metals exist in the form of compounds under normal conditions. But it will be used often.

1.Gold, silver, and jewelry are often used.

2.Iron, such as automobiles, machines, etc., will use iron in large quantities. Many of the pots used for stir-frying are also made of iron.

3.Copper, most of the cores in the wires are copper, and there are also inserts in the sockets, etc. Because the electrical conductivity of copper is second only to silver in nature.

4.Aluminum, pressure cooker, rice cooker liner.

5.Tin, most of the circuit board solder joints of computers or other electronic products are made of tin.

6.Zinc, some high-end door handles, locks, materials are zinc and zinc alloys, the "day" buckle on our leather bags, the zipper pulls on clothes and so on are also zinc products.

7.Nickel, in order to increase its rust resistance, brightness, high-grade, etc., many items will be plated with a layer of nickel on the outside, such as the "day" shaped buckle mentioned in Article 6, such as the commonly used key chain, etc., will be nickel plated. Nickel is also one of several metals that a magnet can attract.

8.Tungsten, tungsten filament in light bulbs is relatively common, and tungsten is also used in large quantities in some electric furnaces. Because tungsten has a particularly high melting point. Nowadays, the use of tungsten light bulbs is decreasing year by year, and is gradually being replaced by energy-saving lamps with lower energy consumption.

9.Titanium, such as some glasses frames, some titanium necklaces, etc.

10.Mercury, which exists in a liquid state in nature, such as mercury in a thermometer, is essentially mercury.

11.Platinum, commonly used in platinum jewelry. It should be more expensive than **.

12.There are other metals that are not mentioned and have not been brought to mind.

Hope mine can help you.

1. Earphone fierce land wire, copper wire for general earphones, silver for high-end earphones. Utilizes the electrical conductivity of metals.

2. Kitchenware, the bottom of modern kitchenware is usually stainless steel. The thermal conductivity and metallic luster of metal are utilized. In the past, China used to use iron pots, which can be ferrous ions attached to food when stir-frying, which is conducive to iron supplementation.

3. In order to prevent the metal from rusting, a layer of chromium or aluminum is often plated on the surface, the former is stable and not easy to react with the components in the air, and the latter generates a dense oxide film. can achieve the effect of protecting metal.

4. The humans of the Iron Age used red copper, bronze and iron to cast sacrificial items and **. It uses the properties of metallic branches that are the ground.

5. Gold and silver can be used to bend currency; Copper elements can be used as wires; Aluminum powder (elemental) can be used as explosives or coatings.

1. Metal elements are the main body of chemical elements and the main material resources for people's production and life.

2. Tungsten (W): Among various metal elements, tungsten is the most difficult to melt and the most difficult to volatilize. Tungsten is mainly used in the manufacture of alloy steel; Pure tungsten is mainly used in the manufacture of tungsten wire in lamps, and is also used in electronic instruments, optical instruments, etc.

3. Chromium (CR): Chromium is a silvery-white metal with extremely high hardness and corrosion resistance, which is used for electroplating and manufacturing special steel. In this century, when people worked on the hard properties of chromium, it was accidentally discovered that it was resistant to corrosion, and stainless steel was born.

Now, stainless steel and chrome-plated products have been widely used in medical equipment, drinking utensils, tableware and other fields.

4. Manganese (MN): Pure manganese is hard and brittle, which is difficult to be applied in production and life, but the alloy of manganese has a wide range of uses. Manganese steel is both hard and tough, making it an ideal material for making rails, bearings, and armor plates.

5. Lithium (Li): Lithium is the lightest metal element with the largest specific heat. Lithium is not only used in the manufacture of ultra-light alloys and lithium batteries, but is also an important material for cutting-edge technologies.

Lithium alloy can greatly reduce weight and energy consumption in the aerospace industry, and plays an important role in the atomic energy industry. In the metallurgical industry, lithium is often used as a deoxidizer and degasser to eliminate porosity and bubbles in metal castings.

6. Titanium (Ti): The specific strength of titanium (the ratio of strength to specific gravity) is the highest among all metal elements. Titanium and titanium alloys are new structural materials, hard and light, mainly used in the manufacture of aircraft, submarines, corrosion-resistant chemical equipment and various mechanical parts.

Titanium alloy can maintain high strength in the temperature range of -253 500 °C, which is an ideal aerospace material. In steelmaking, a small amount of titanium is also a good deoxidation, nitrogen removal and desulfurization agent.

1. Tungsten: Among various metal elements, tungsten is the most difficult to melt and the most difficult to volatilize metal element, tungsten is mainly used to make alloy steel, pure tungsten is mainly used to make tungsten wire in lamps, and is also used in electronic instrument key lifter, optical instrument, etc.;

2. Chromium: Chromium is a silvery-white metal with extremely high hardness and corrosion resistance, which is used for electroplating and manufacturing special steel, stainless steel and chrome-plated products have been widely used in medical equipment, drinking utensils, tableware and other fields;

3. Manganese: pure manganese is hard and brittle, and it is difficult to apply in production and life, but the alloy of manganese has a wide range of uses, and manganese steel is both hard and tough, which is an ideal material for manufacturing Sohui rails, bearings, and armor plates;

4. Lithium: Lithium is the lightest and the largest specific heat metal element, lithium is not only used to manufacture ultra-light alloys and lithium batteries, but also is an important material for cutting-edge technology, lithium alloy in the aerospace industry can greatly reduce weight and reduce energy consumption, in the atomic energy industry has an important role, in the metallurgical industry, Shixiao lithium is often used as a deoxidizer and degassing agent, in order to eliminate the pores and bubbles in metal castings.

1. Silver: silver coins, electronic devices, fillers used by dentists.

2. Gold: ornaments, gold coins.

3. Aluminum: cables, aluminum cans, aluminum windows.

4. Copper: wires, musical instruments, water pipes.

5. Iron: railways, boats, iron bridges, railings.

6. Zinc: plated on the surface of iron, so that the iron is not easy to rust.

7. Tin: Tin is plated on the mild steel to prevent the mild steel from coming into contact with oxygen and people, and slow down the rusting speed of the steel.
