Aluminium is a silver white light metal that possesses great strength and non-rusting quality. It
can be hammered or pressed into new shapes. It can take a high polish. About 8 percent of the
earth's crust is aluminium. It is found combined with other elements for the most part in an ore
called 'bauxite'.
The first deposit of bauxite was discovered near 'Les Baux', a town in France. Hence the ore is
known as bauxite. By crushing, grinding and treating chemically, the bauxite is changed into 'alumina'
a white powdery material.
Sir Humphry Davy, a British chemist, was the first to realise that aluminium could be obtained
from this white powder called 'alumina'. He named the metal as aluminium in 1807.
Aluminium has a great variety of uses. Railways are now using passenger coaches chiefly
made of aluminium. As the metal weighs only one-third of steel, the locomotive can pull a large
number of coaches. Because of its non-rusting quality aluminium has become an ideal material for
the production of cooking utensils and for bridge construction. The world's first aluminium bridge,
a 27 meter span covering a railway track and a road was built in Suderland, Britain in 1947. Aluminium
containers are used for cosmetics and tooth-pastes. Due to its lightness and strength aluminium is
used to make airplanes and automobiles. It is also used as a protective coating or plating on steel.summary writing
