What is the difference between cast iron and pig iron?

Cast iron and pig iron are both types of iron that have different properties and are used for different purposes. Here are the differences between them:

Composition:

Pig iron is the crude iron that is obtained directly from a blast furnace. It contains a high percentage of carbon (up to 4.5%) and other impurities such as sulfur and phosphorus. Cast iron is a type of iron that is derived from pig iron, but with a lower carbon content (typically between 2.1% and 4%) and other added alloying elements such as silicon.

Properties:

Pig iron is a brittle and hard material that is difficult to work with. It has a high carbon content, which makes it susceptible to cracking and breaking. Cast iron, on the other hand, is more malleable and ductile than pig iron. It has a lower carbon content, which makes it more workable and easier to shape.

Uses:

Pig iron is primarily used as a raw material for the production of cast iron and steel. It is also used in the manufacturing of iron-based products such as pipes, fittings, and automotive parts. Cast iron, on the other hand, is used for a variety of applications such as engine blocks, cookware, and decorative elements.

In short, pig iron and cast iron are two different types of iron that have different properties and uses. Pig iron is the crude iron that is obtained directly from a blast furnace, while cast iron is derived from pig iron with added alloying elements and a lower carbon content. Cast iron is more malleable and workable than pig iron, and is used for a variety of applications such as engine blocks and cookware.
