-:..An iron-carbon alloy with a carbon content of more than %. Industrial cast iron generally contains % to % carbon. Carbon mostly exists in the form of graphite in cast iron and sometimes in the form of cementite. In addition to carbon, cast iron also contains % to % of silicon and elements such as manganese, phosphorus, and sulfur. Alloy cast iron also contains elements such as nickel, chromium, molybdenum, aluminum, copper, boron, and vanadium. Carbon and silicon are the main elements that affect the microstructure and properties of cast iron.
