Ductile Cast Iron

Ductile cast iron, other name ductile iron, nodular cast iron, spheroidal graphite iron, spherulitic graphite cast iron and SG iron, is a type of cast iron widely used in casting parts. With its nodular graphite inclusions, ductile cast iron has much more impact and fatigue resistance, different from the most varieties of cast iron which are brittle.

Through control of the microstructure, ductile cast iron can be produced to have a wide range of properties. The most common usage of ductile cast iron is in the form of ductile iron pipe, such as the hydraulic parts, which is heavier than the polymeric materials such as PVC, HDPE, LDPE and polypropylene, but requires less careful installation and protection from physical damage. Besides, ductile cast iron is specifically suitable for making many automotive components, where strength needs surpass that of aluminum but do not necessarily surpass steel. Other major industrial applications include off-highway diesel trucks, agricultural tractors, and oil well pumps and valves.
