Ductile iron is produced by treating molten low-sulfur base iron with magnesium under closed controlled conditions. In ductile iron, the graphite exists in the form of spheroidal shape, which has little influence on weakening the matrix and resulting in centralizing strain, so ductile iron possesses good flexible property. While, in grey iron, the graphite is present in flake form, which has the effect of cutting the iron matrix and making it become brittle and easy to crack.
