1. Soldering. Solder: It mainly refers to the solder with a low melting point made of tin-based alloys. With the development of the industry and the introduction of EU environmental protection requirements, the gradual replacement of lead solder by lead-free solder is an inevitable trend in the development of the global electronics manufacturing industry.
At the same time, tin solder is the main application of tin in the electronics industry, used for electronic soldering, which currently accounts for 70% of the downstream applications of tin in China, and tinned steel plates and tin chemicals account for 8% and 12% of the downstream applications respectively.
2. Tin plate.
Tin plate: commonly known as tinplate, has good sealing, preservation, light protection, firmness, corrosion resistance, non-toxic and has a unique metal decorative charm, is widely used in food packaging industries such as canned food, beverages, military, instrumentation, electrical appliances and other industries.
Among them, in the field of packaging, it is an internationally used packaging variety. Tin plate is also one of the important areas of tin consumption, accounting for 30% of its total consumption (2010 data).
3. Tin alloy.
The most common alloys are tin-based bearing alloys made of tin and antimony and copper, and lead-based bearing alloys composed of lead, tin and antimony, which can be used to make bearings for steam turbines, generators, aircraft and other mechanical equipment that are subjected to high speed and high pressure. At present, tin-containing bronze is mainly used to make wear-resistant parts and corrosion-resistant equipment, and is widely used in shipbuilding, chemical, construction, currency and other industries.
Tin brass can be formed by adding tin to brass, which is mostly used in the manufacture of ship parts and welding rods, etc., and is known as "navy brass". In industry, tin is also often plated on copper wires or other metals to prevent these metals from being corroded by acids and alkalis.
Tin can also be made into movable type alloys with other metals (lead will gradually be phased out with the spread of laser printing technology), babbitt alloys, titanium-based alloys and niobium-tin alloys, etc., which are used in cutting-edge technology fields such as the atomic energy industry, the aviation industry, superconducting materials and spacecraft manufacturing.
4. Chemical industry. Tin is mainly used in the chemical industry to produce tin compounds and chemicals. The organic compounds of tin are mainly used as wood preservatives, pesticides, etc., and the inorganic compounds of tin are mainly used as catalysts, stabilizers, additives and emulsifiers in the ceramic industry.
5. Tin compounds.
Tin sulfide, a compound of tin and sulfur in the crystal structure of selenium dioxide, is similar in color to gold and is often used as a golden pigment. Tin dioxide, a compound of tin and oxygen, is a water-insoluble white powder that can be used to make enamels, white glazes and opalescent glass.
Tin dioxide can also be used as a catalyst to prevent air pollution – car exhaust often contains toxic carbon monoxide gas, which can be largely converted to carbon dioxide at 300 degrees Celsius. Tin compounds can also be used in dyes, rubber, plastics, pesticides and other industries.
6. Chemicals.
Tin chemicals are another major end-use of tin. In recent years, the consumption of tin in the chemical field has been increasing. There are five main areas of tin for chemical use: PVC heat stabilizers, pesticides, catalysts, agricultural fertilizers, and glass coatings.

Usually, people use tin foil to package cigarettes and candies to prevent moisture (in recent years, China has gradually replaced tin foil with aluminum foil. Aluminium foil is easy to distinguish from tin foil – tin foil is much brighter than aluminium foil). However, the ductility of tin is very poor, and it breaks when it is pulled and cannot be drawn into filaments.

The metal tin is mainly used to make alloys. Tin was often used to make bronze in ancient China. The ratio of tin to copper is 3:
7。Tin is a softer metal with a low melting point and strong plasticity. It can be made into a variety of styles with a variety of finishes, from traditional and elegant European wine utensils, candlesticks, noble and generous tea sets, to vases and delicate table ornaments, all of which are comparable to glittering silverware.
Features: The ordinary form of white tin is a low melting point metal with silvery-white luster, which is divalent or tetravalent in the compound, and will not be oxidized by air at room temperature, mainly in the form of dioxide (cassiterite) and various sulfides (such as thiossiterite) in nature. Tin is one of the famous "hardware" - gold, silver, copper, iron, and tin.
Tin has been discovered and used since ancient times. In some ancient tombs in our country, some tin pots, tin candlesticks and other tin utensils are often excavated. According to research, during the Zhou Dynasty in China, the use of tin ware was very common.
In ancient tombs in Egypt, daily necessities made of tin have also been found.

The birth of the Internet can be traced back to the late 60s and early 70s of the 20th century, when the U.S. Department of Defense laboratory connected the major computers in the department and adopted rules to enable the exchange of information between users. This is the birth of the Internet; By 1972, the system had connected 50 universities and research institutes. But the real development of the Internet began in 1985.

Chinese Simplified is a standardized way of writing in modern Chinese, as opposed to Chinese Traditional (also known as orthodox Chinese). Chinese Simplified Chinese is mainly composed of inheritance characters and simplified characters that began to be implemented in Chinese mainland after the 1950s.

In the past 30 years, scientists have used radioisotope dating to obtain a series of data related to the age of the earth: zircon obtained in the rocks of Western Australia has been measured to be 4.2 billion years old, although this zircon is redeposited in Mesozoic rocks, it is enough to show that the age of the earth is not less than this data; Many of the rocks obtained from the Moon are more than 4.6 billion years old, and since the Moon is a satellite of the Earth and a member of the solar system, the age of the Earth should not be less than the age of the Moon; The ages obtained from a large number of meteorites from the solar system are also between 4,64.7 billion years. According to the basic principle of the identity of the origin of the solar system, the age of the Earth should be more than 4.6 billion years. >>>More
