If you study different types of metals, you will probably come to the question of what exactly tin is.
What tin is and what properties it has
Tin is a chemical element with atomic number 50 in the periodic table and the symbol Sn. It is one of the oldest metals used by humans and still plays an important role in various industries today.
- Tin is a metal with a density of about 7.31 g/cm³, which makes it a very soft heavy metal. Due to its high malleability, also called ductility, tin can be rolled into thin sheets or foils, which is useful for various industrial applications.
- The melting point of tin is around 231.9 °C and is therefore relatively low compared to other metals. This property makes tin ideal for solder alloys, as it can be processed at low temperatures.
- At room temperature, tin is very resistant to many environmental influences, especially air and water. This corrosion resistance makes it particularly popular for protecting other metals from oxidation, e.g. when tinning iron.
- The metal's electrical conductivity is not as good as that of copper or silver. However, it can at least conduct electricity well enough for many products.
- Because it is very easy to work with, tin is often used to make cans or decorative items. By simply bending and cutting it, it can be made into many different shapes without much effort.
The importance of tin in industry
Tin has had a firm place in industry for many years. Its versatility and ability to react with other metals make it an important component in many industrial processes.
- One of the most important applications of tin is solder used in the electronics industry. Due to its low melting point and good adhesion, it is ideal for connecting components on printed circuit boards.
- The metal is also often used to protect steel from corrosion. The thin layer of tin prevents the underlying steel from rusting.
- Tin is a main component of bronze, along with copper. This alloy is known for its hardness and durability and is used to make sculptures, coins and machine parts.
- Tin is also used in surface finishing to coat metals and protect them from wear and corrosion. For this reason, it is also often used in the automotive, construction and food industries.
