Cast iron is an iron-carbon cast alloy with other elements that is made by remelting pig iron and other additions which is defined as a cast alloy with carbon content that ensures the solidification of the final phase with a eutetic transformation. Depending on chemical specifications, cast irons can be non-alloyed or alloyed. The range of alloyed irons is much wider, and they contain either higher amounts of common components, such as silicon and manganese or special additions, such as nickel, chromium, aluminum, molybdenum, tungsten, copper, titanium, and others. Generally speaking, the cast iron could be divided into gray iron, ductile iron (nodular iron), white cast iron, compacted graphite iron and malleable cast iron.
