Why aeroplanes are made up of aluminium?

 First off all the aircraft or aeroplanes are made up of aluminium due to some special characteristics of the aluminium.The aluminium is quite lighter than the rest of the metals it has only roughly third the weight of the steel.It also help to be aircraft more fuel efficient.It is much more stronger as compare to its weight.

Aluminium also resist corrosion caused during rainy season.

Thank you
