.Aluminum
Aluminum is a silvery-white metal. It is not found free in nature, but
is the most abundant metal in the Earth's crust (8.1%) in the form of
minerals such as bauxite and cryolite.
The advantage of Aluminum:
1.It is hard and strong.
2.Aluminium have high corrosion resistant because it have a protective oxide layer.
3.It has low density, can be easily cast, machined and formed.
The disadvantage of Aluminum:
Although aluminum has a high conductivity, it will not be use
in electrical transmission lines, because it has low density and expensive.
The use of Aluminum:
Aluminum extensively used for kitchen utensils, outside building
decoration and in any area where a strong, light, easily constructed
material is needed.
