The density of ductile iron
- on Sep. 15, 2011
The density of ductile iron is
approximate 7.3 g/cubic centimeter,
or 7.3 kg/liter, or 119.6 g/cubic
inch. However, the density has a
range of variation because of the
material degrees and shrinkage
The Types of Ductile Iron

elongation of ductile iron, the
silicon’s content is low, the matrix
is completely ferrite. Its
elongation is more than 20% and its
high fatigue strength is more easily
meet the design requirements.
