    - Alloys which have iron as main constituent are called as ferrous alloys.

    - Cast iron is an alloy of iron, carbon and silicon.

    - Cast iron can be casted into intricate shapes because high carbon content in cast iron makes molten iron very fluid. Hence it is easy to pour them into intricate shapes. The carbon content in cast iron is 1.7% to 4%.

    - Cast iron has poor tensile strength and is lower than compressive strength.
