Ductile Iron Shell Castings
Ductile iron is popular and welcome by the shell mold casting process. Ductile cast iron obtains the nodular graphite through processes of spheroidization and inoculation treatment, which effectively improves the mechanical properties, especially the plasticity and toughness, so as to obtain higher strength than carbon steel. Ductile cast iron is a high-strength cast iron material with its comprehensive properties are close to steel. Based on its excellent properties, the ductile iron has been successfully used for casting parts of complex forces, strength, toughness and wear resistance. Ductile iron is often used to produce parts for crankshafts and camshafts for automobiles, tractors, and internal combustion engines, as well as medium-pressure valves for general machinery.
