Definition - What does Cast Iron mean?
Cast iron is one of the group of carbon-iron alloys that can easily be molten and poured (casted) into any desired shape due to its 2% carbon content. Cast iron is preferred for manufacturing equipment or materials whose melting point temperature must remain low during their operation.
Corrosionpedia explains Cast Iron
There are two types of cast iron available for manufacturing purposes:
- White cast iron is a type of cast iron in which the carbon content is present almost 2% more than a simple alloy in the form of cementite. For this reason, when white cast iron is fractured, it exhibits a whitish-silver like fracture.
- Grey cast iron is a type of cast iron in which the carbon content is present almost 2% more than a simple alloy in the form of a graphitic microstructure. Due to the presence of graphite, it is relatively inexpensive, durable and easily malleable.
