There are several advantages that ductile iron provides designers:
Ductile iron can be easily cast and machined.
It has an excellent strength to weight ratio.
Ductile iron can be made for a much lower cost than steel.
It has superior castability and machinability.
Ductile iron provides a designer with an exceptional combination of toughness, low cost manufacturing, and reliability.
Ductile Iron Applications
Ductile iron has greater strength and ductility than gray iron. Those properties allow it to be used effectively in a wide variety of industrial applications, including pipe, automotive components, wheels, gear boxes, pump housings, machine frames for the wind-power industry, and many more. Because it does not fracture like gray iron, ductile iron is also safe to use in impact-protection applications, such as bollards.
