cast iron: A group of iron alloyscontaining 1.8 to 4.5% of carbon. It isusually cast into specific shapes readyfor machining, heat treatment, or assembly.It is sometimes produced directfrom the blast furnace or itmay be made from remelted pigiron.

Alloys of iron and carbon made by remelting the crude iron produced in a blast furnace. The carbon content is usually between 2.4 and 4.0% and may be present as iron carbide (white cast iron) or as graphite (gray cast iron). Metals can be added to improve the properties of the alloy. Additional elements such as phosphorus, sulfur, and manganese are also present as impurities. Cast iron is a cheap metal with an extensive range of possible properties and it has been used on a very large scale.
