The engineering materials Classified below figure.
Having defined the limits of materials that come under our purview, we can classify them two broad groups according to the nature.
1.Metals
2.Non-Metals
Metals are familiar objects with a characteristic appearance they are capable of changing their shape
permanently, and have good thermal and electrical conductivity.
Non-Metals contains no metal in their substances. But Thermal conductivity,electrical conductivity resisted.
Ferrous Materials contains Iron as main material.And Non Ferrous Materials No contains Iron.
An alloy is a combination of more than one substances.
