Ductile Iron Metal Casting Resources

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 ...

Metallography of cast iron insight Struers

The term cast iron refers to iron-carbon-silicon alloys that contain 2.5-4 % carbon and usually 1-3 % silicon. In grey irons, the carbon is present as graphite; in white cast iron it is present in the form of iron carbide and alloy carbides. Cast iron has good castability and machinability, as well as moderate mechanical properties.

Flexible Iron? Ductile Iron vs. Cast Iron Castings Blog

Ductile iron is less brittle than other cast iron, even before heat treatment. It does not fracture as easily with impact. Being ductile allows the iron to bend. In comparison, gray cast iron is harder. This hardness means that it manages surface wear well. Gray iron is also better at vibration damping.
