Cast iron is a material derived from pig iron with 2 to 4 weight percent of carbon, as well as a high silicon concentration.
Cast irons are broken into gray and white. White cast iron has a high cooling rate and a low carbon equivalent, while gray cast iron has a low cooling rate or a high carbon equivalent.
Cast iron is commonly used because it costs very little to make.
whereas
Most pig iron is made by the reduction of iron ore in blast furnaces. Coke or charcoal are the most common agents used to reduce the ore. The makers of pig iron either use it to make other metals or resell to external customers to melt down. Pig iron is not often used to craft utensils of any sort because it is weak and brittle.

pig iron contains 4% of carbon as impurity and cast iron contains 2.11% impurity this creates difference between both of them
