Areas and fields of tin and tin alloy use

Tin is one of the first metals known to humans. For more than one millennium, tin and its alloys have been actively used in different spheres of human activity thanks to their properties.

Tin and Its Alloys

In Mendeleev’s periodic table, the light metal tin is designated by the symbol Sn. This is a silvery-white substance, fusible because of its low melting temperature. It can easily be rolled into a thin layer of foil because of its ductility and plasticity. This substance is resistant to water and some acids. These properties allow tin to be used for producing many products.

This metal oxidizes slowly under normal conditions, so it is used for protective coatings. As an independent metal, tin is used less often than its alloys. This is because alloys can have more suitable mechanical and technological properties. The compound of tin and copper is called bronze. It is one of the most frequently used tin alloys.

Tin Application Area

Tin is most often used as a protective coating. More than 40% of all tin goes to the production of tinplate containers, more precisely to tinning them. Tinning is the process of applying this metal to the surface of a metal product to protect it from corrosion. Tin’s anti-corrosion properties also made it possible to use it for pipe production.

The light metal is also used in dentistry for producing dental fillings. Tin dishes were used even in ancient times, because people already knew about their rust-resistant properties. But because this metal was expensive, such dishes never became popular in everyday life.

Fields of Application of Tin Alloys

As mentioned earlier, alloys are more popular than tin itself. There are more than ten thousand of them. Industry consumes huge reserves of alloys every year. Why? Additional properties useful in manufacturing products allow alloys to be used in many areas.

Fields of application of tin alloys:

• Solder production. Tin alloys with cadmium, lead, bismuth and other metals are used to produce solders. They are used for soldering parts and blanks because such alloys are sufficiently strong and fusible.

• Printing. If antimony is added to an alloy of lead and tin, the result is a material used to create type for printing.

• Automotive industry and aircraft construction. Bearings of various sizes and different parts for cars and aircraft are made from an alloy of tin, copper, lead and antimony, called babbitt. Babbitt alloy is characterized by good wear resistance.

• Decorative and applied art. The alloy of tin and copper, bronze, is used to create different sculptures and monuments. Bronze is not affected by environmental factors and is therefore considered a durable material well suited for such purposes.

• Shipbuilding and instrument engineering. Tin alloys, because of their anti-corrosion properties and mechanical resistance, are well suited for producing parts that should not wear out quickly or lose the ability to perform their functions.

Undoubtedly, tin and its numerous alloys have very broad areas and fields of application. Use in medicine, the automotive industry, shipbuilding, instrument engineering, aviation and decorative applied art makes tin and tin alloys some of the important elements in human activity.
