A:The primary difference is the alloy process. In the case of cast iron, the carbon forms graphite in the form of flakes and can be seen when fractured giving it the “gray” appearance. For ductile iron, a small amount of magnesium is added to molten iron, which causes the graphite to form in “nodules” or spheres.
