Ductile cast iron by coated resin sand casting has better strength to weight ratio, better machinability and higher impact value. Moreover, the ductile iron complex parts can be achieved compared to forging. Thus many auto parts such as crank shafts, connecting rods manufactured usually by forging is increasingly being replaced by ductile iron casting. When graphite is present as small, round, well-distributed particles, with higher ductility.
