Uses of Metals

Metals does not actually have a solid definition since it is a broad term. However, they are usually described as substances with high electrical and thermal conductivity as well as malleability and lustre. Metals usually loses its electron to form positive ions known as cations.

Metals form the largest group in the periodic table and they are also defined according to their position in the periodic table. They are grouped as alkali metals, alkaline earth metals, transition metals, heavy metals and rare earth metals. On the basis of hardness, metals are also distinguished as used metals and non-metals. Usually metals are extracted from their ores in the process called refining.

Different uses of Metals

  • In electronics
  • In medicine
  • Machinery, Refractory and Automobiles
  • Decorative products
  • Other Uses

In the Construction Industry

Metals are the main component in the construction industry. Metals like iron, steel amongst others are the main materials used in construction of buildings and even homes.

In Electronics

Another important application of metals are in electronics. As metals are good conductors of electricity, they are used to make wires and parts for equipments and gadgets that function on electrical current. Popular examples include, TV, mobiles, fridge, iron, computers etc.

In medicine

If you are wondering how, well from a biological perspective metals are found as micro-elements in our bodies. Besides, the presence of metal elements is crucial for several functions like transmission of nerve impulses, oxygen flow, reaction between enzymes etc. Some medicines are therefore liaised with metal compounds to treat certain deficiencies or sickness. Metals like, iron, calcium, magnesium, potassium titanium, and aluminum are used commonly in medicine in the form of antacids.

Apart from this, most of the equipments and tools used are made from metals.

Machinery, Refractory and Automobiles

This is one of the most common use of metals. They are used extensively in manufacturing machines for industries, agriculture or farming and automobiles which include road vehicles, railways, airplanes, rockets etc. Here, the commonly used metals are iron, aluminum and steel.

Besides these, most of the utensils that is used in the kitchen are made from metals like steel, aluminum, and copper. Due to a high temperature withstanding nature metals are preferred the most.

Decorative products

Metals such as platinum, gold, and silver come under the category of precious metals and have high economical value. These metals are widely used in making jewelry sets or for some decorative piece.

Other Uses of Metals

Some of the other uses and applications of metals are, they play an important role in security as the metals are used in making locks, strong safe, doors etc. Apart from this, furnitures are made from metal these days. Metals also find their uses in the military where they are used to manufacture weapons and ammunitions. Some metals are used in galvanising to protect from rusting.

These are some of the popular uses of metal. To know more about metals, different types, properties of metals and more you can keep visiting BYJU’s or you can also download our app for interesting content and learning experience.
