What is the material of cast iron?
Cast iron is an iron-carbon alloy with a carbon content greater than 2.11%. It is made of industrial pig iron, scrap steel and other steel and alloy materials through high-temperature melting and casting. In addition to iron, carbon in other cast irons is also precipitated in the form of graphite. If the precipitated graphite is flaky, this cast iron is called gray cast iron or gray cast iron, worm-like cast iron is called vermicular graphite cast iron, flocculent cast iron is called malleable cast iron or cast iron, and spherical cast iron is called nodular cast iron.
