Ductile Iron Castings & Ductile Cast Iron
If cast iron is subject to a compressive load, these stress points are not particularly detrimental and flake graphite cast iron is excellent under compression. However, tensile loading above the natural tensile strength of the cast iron can cause rapid tensile failure as cracks propagate rapidly out from these stress points. The result of this is that cast iron has virtually no elongation, is a brittle material and is therefore limited in its use in tensile and shock loading applications. For years foundrymen and metallurgists tried to develop a new type of cast iron that would withstand bending and shock loading and would have the characteristics more of malleable cast iron but could be produced at the lower cost of grey cast iron. This resulted in the development of Ductile Cast Iron.
The main products includes small wheel hub, reducer shell, differential shell, ductile iron brackets, idle wheels, and flywheels.

If you were to do a chemical analysis of ductile iron, this is what you would normally find:
Carbon 3.2 – 3.60%
Silicon 2.2 – 2.8%
Manganese 0.1 – 0.2%
Magnesium 0.03 – 0.04%
Phosphorus 0.005 – 0.04%
Sulfur 0.005 – 0.02%
Copper <= 0.40%
To improve the strength of ductile iron, additional tin or copper can be added. To improve corrosion resistance, copper, nickel, or chromium can replace anywhere from 15-30% of the iron.
Common Ductile Iron Grades
While there are many different ductile iron specifications, foundries routinely offer 3 common grades;
