Importance of Metal

This period in which we are living has been called the ran Age. There is hardly a single moment of our daily lives in which iron does not play an important part. Our food, our buildings, vessels, means of transports. Our luxury articles-iron is necessary for them all.

All materials which we posses are obtained from the earth or from nature in their raw forms. It is our ability to convert these raw materials into useful articles of consumption. The materials chiefly used in the shops are metals, and these are divided into two groups, ferrous and non-ferrous. The iron group which includes all irons and steels are called ferrous metals, whilst the others are called non-ferrous.
