INFO ABOUT DUCTILE IRON CASTINGS

Cast in Green Sand Molds

Ductile Iron, also known by many other names such as, ductile cast iron, nodular cast iron, spheroidal graphite iron, etc. Because of its nodular graphite rich inclusions, it is known for its fatigue and impact resistance. Ductile iron castings are strong.

What truly defines the group of materials that make up Ductile Iron is the structure of its graphite. Unlike the graphite flakes in Gray Iron, the structures of the graphite in Ductile Iron are nodules. These rounded nodules inhibit the formation of cracks. This characteristic provides increased ductility; hence the name Ductile Iron.

Annually, the majority of the produced Ductile Iron is in the form of ductile iron pipe. Unlike its light-weight counterparts, PVC, HDPE, LDPE and other polymeric materials. Ductile Iron, when used for sewer and water lines, offers much more resistance to physical damage.

In the automotive industry, it is used for components that require a material other than steel but is stronger than aluminum. For projects that are large and complex and require extreme fatigue loads, nodular cast iron is used. Other uses for Ductile iron castings include oil well pumps, Class 8 trucks, hubs and structural parts, etc.
