Aluminium is extracted from its ore called bauxite. It looks like dark reddish colored rock. 4 to 6 tonnes of bauxite can give about 1 tonne of aluminium. Therefore, bauxite is a bulky raw material. Most of the airplanes are made from aluminium which is a light metal. Aluminium is highly malleable, which means that it can be shaped into different forms easily, and it becomes stronger when mixed with other metals.
