The density of ductile iron
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 grades and
In short words, if the iron foundry used more good pig iron, and
less shrinkage, then the ductile iron density will be higher,
otherwise, it will be lower. So, it has a range from 7.1 to 7.3
Iron foundries normally
estimate the weights of rough castings by calculating the volume of
ductile iron castings, so the density will be used. However, you can
not judge the casting quality just by the density.
There are many more
factors that can affect it, such as spheroidization rate and cooling
speed etc., so it will be reasonable in the range.
