What is an alloy? Mention its advantages. Mention the name of three alloys and also mention the components in them, properties and uses.

Alloys are the homogeneous mixture of 2 or more metals or metal and non-metals.

By making alloys there are changes in the properties of the element which is advantageous to us such as:

•It makes them hard and stronger. For e.g. steel (alloy of iron and carbon)

•Some of the alloys lowers the melting point which makes them easily fusible and this property is used in solders.

•Alloys of aluminium are light and stronger which are used in aeroplanes.
