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

i. Ferrous metals: These are metals that contain iron. As such, they can be attracted to any magnetic substance, which means they are magnetic. Examples include steel, cast iron, wrought iron, mild steel, and stainless steel.

ii. Non-ferrous metals: These are metals that do not contain iron. They cannot be attracted to any magnetic substance, which means they are non-magnetic. Examples include aluminium, copper, zinc, tin, gold, etc.

When two metals are mixed together to produce a mixture that has properties different from those of the original metals, the product is called an alloy. Alloys with iron content are called ferrous alloys, while those without iron content are called non-ferrous alloys.
