Classification of Metal

Metals are classified into two groups, namely, ferrous and non-ferrous metals.

1. Ferrous Metals:

Ferrous metals are metals that contain iron as the primary element, as such, they can be attracted to any other magnetic substance. They are known for their mechanical properties, such as high tensile strength. They can be easily shaped or formed.

The word ferrous derives from the Latin word ‘ferrum’, which means iron (chemically known as Fe).

Examples include stainless steel, iron, razor blade, cast iron, wrought iron, etc. They are widely used in construction, automotive and manufacturing industries due to their strength and durability. They are suitable for architectural and structural uses such as skyscrapers, bridges and railways.

They are prone to rust and therefore require a protective finish, which is sometimes used to improve the aesthetics of the product it is used for as well.

2. Non-ferrous metals:

Non-ferrous metals are metals that do not contain iron. They cannot be attracted to any other magnetic substance. They do not rust. Examples include aluminium, copper, lead, zinc, tin, silver, gold, etc.

Non-ferrous metals are rarer, more valuable and resistant to corrosionCorrosion is defined as a natural process that causes the transformation of pure metals into undesirable substances when they react with substances like water or air. This reaction causes damage and... More than ferrous metals.
