Grey cast iron

Contains 1.7 to 3.5% carbon in Free State and is obtained by the slow cooling of molten cast iron

Is produced by annealing process. I is soft, tough and easily machined metal

Is also known as chilled cast iron is obtained by cooling rapidly. It is almost unmachinable

Is produced by small additions o magnesium (or cerium) in the ladle Graphite is in nodular or spheroidal form and is well dispersed throughout the material

Engineering Materials
Thermoplastic materials are those materials which

Do not become hard with the application of heat and pressure and no chemical change occurs

Are flexible and can withstand considerable wear under suitable conditions

Are formed into shape under heat and pressure and results in a permanently hard product

Are used as a friction lining for clutches and brakes
