Cast iron has low percentage of elongation it is brittle material and it is used in lathe bed that's why it having high compression.

White cast iron is very hard and brittle, so it can not be machines properly. It is the only member from cast iron family where carbon is presented only as carbide. For the presence of different types of carbide and less present of silicon it is extremely hard and brittle so lacks tensile strength.

White cast iron is hard and brittle, hence it high compressive strength with corresponding poor strength under tension as generally associated with brittle materials.
