Ductile iron castings have many advantages

Ductile iron – also referred to as spheroidal or nodular iron – is actually a group of irons that exhibit high strength, flexibility, durability and elasticity due to their unique microstructure. Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted or deformed without fracturing. Its mechanical properties are similar to steel, and far exceed those of standard cast irons.

Ductile iron castings are solid metal objects that result from molten ductile iron being poured into voids in a mold. The ductile iron subsequently cools and solidifies in the shape of the void it occupies.


What is in Ductile Iron? (Composition)

If you were to do a chemical analysis of ductile iron, this is what you would normally find:

Iron ~94%

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;
