Cast iron refers to an iron carbon alloy with a carbon content of 2% or more. Cast iron used in industry generally has a carbon content of 2% to 4%. Carbon exists mostly in the form of graphite in cast iron, and sometimes also in the form of cementite. In addition to carbon, cast iron also contains 1% to 3% silicon, as well as elements such as manganese, phosphorus, and sulfur. Ductile iron is obtained by spheroidizing gray cast iron molten iron, and the precipitated graphite is spherical, abbreviated as ductile iron. It has higher strength, better toughness, and plasticity than ordinary gray cast iron. Used for manufacturing internal combustion engines, automotive components, and agricultural machinery.
