Cast Iron is an alloy of iron and carbon, and is popular because of its low cost and ability to make complex structures. The products of cast iron exhibit reasonable resistance against corrosion, deformation and provide a rigid frame. Carbon is present in the form of plates in gray cast iron, whereas, it is in the form of sphere shaped graphite particles in ductile cast iron, which shows better tensile strength and strain than gray cast iron.Ductile iron is a valuable structural material, which depending on its matrix offers a wide range of mechanical properties, with simultaneously a good wear resistance and a good ability to absorb the mechanical vibration. Considering these properties and production costs, it is apparent in many cases, that castings with nodular graphite can be the substitute to more expensive forged steels.
Cast irons have a wide range of applications, including machine and car parts like cylinder heads, blocks and gearbox cases, cookware, pipes, etc.
