What are the disadvantages of cast iron?
Disadvantages of cast iron
It is Prone to rusting.

Its parts are section sensitive, this is due to slow cooling of thick sections.
failure of Its parts is sudden and total, it does not exhibit yield point.
It has poor impact resistance.
Compared to steel it has poor machinability.
What are the 5 types of cast irons?

To perform a spark test, you will need to apply a sample of the material at hand to an abrasive wheel, which will cause sparks to shoot out.
Is cast iron steel?
Cast iron is actually an alloy of iron and carbon, just like steel, with the main difference being that cast iron has more carbon in it.
Whereas steel requires a carbon content of no more than 2 percent, cast iron usually contains 2 to 3.5 percent carbon.
How strong is cast iron?
Strength. The compressive strength of cast iron is 6.3 – 7.1 tonnes / sq. cm. It’s ultimate tensile strength is 1.26 – 1.57 tonnes / sq.
