                       Cast iron which is mainly contain carbon and iron as like as a steel. In a cast iron amount of carbon is 2 to 6.67 %. In iron-iron carbide schematic figure or diagram we find carbon amount is larger than which is needed to eutectic temperature. When in a cast irons carbon is used more these types of cast iron is brittle, for this reason when cast iron produce in commercially carbon used is a less amount such as 2 to 4 %. For rigidity of cast iron it’s   malleable is low and it can not be easily reeled   at room temperature and easily one from to another from for uses various purpose. For giving various shape of cast irons people use casting process   which melt cast iron at high temperature.   And finally for smooth surface it machined.   Cast iron is cheap and availability is high, one can do properly heat treatment,   control is better in foundry shop, alloy can produce properly.   In metallurgy cast iron classified of four types   in physically such as
