Ductile Iron
Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spherulitic graphite cast iron, and SG iron, is a type of cast iron. Ductile iron is part of a group of materials that can have a wide range of properties through control of micro-structure. The common defining characteristic is graphite. Ductile iron received its name due to the creation process. The graphite is nodule form rather than flake, like in grey iron. The sharp shape of the graphite flakes inhibit cracks and provide enhanced ductility, hence ductile iron. While most varieties of cast iron are brittle, ductile iron has …
