Cast iron contains 2.1%-4.3% carbon. By increasing carbon content in material, it becomes more brittle why because carbon atoms are small compare to iron so they occupy the octahedral voids of iron and they fill the vacancies.

As the carbon content increases material becomes more brittle/hard. In the cast irons carbon content is more than 2% so which is more brittle than steel.

It is lack of ductility. Brittleness implies that it can not drawn out by tension to smaller section. Ordinary glass is nearly ideal brittle material.

Cast iron contains more amount of carbon which makes it loose its ductility and it becomes hard and brittle.

Cast iron contain 2 to 4% carbon which makes it brittle in nature.

Cast iron has a maximum amount of carbon so it becomes brittle.

Because the carbon% is more making them tough and brittle too.
