Thus, white iron is hard and brittle and has a white crystalline fracture because it is essentially free of graphite. White iron has a high compressive strength and excellent wear resistance, and it retains its hardness for limited periods even up to a red heat.
Ductile Iron is a unique engineering alloy that is similar to gray iron except that it is not brittle. The material is able to flex and has more fatigue resistance than gray iron. These properties are a result of creating graphite nodules instead of graphite flakes during solidification. Ductile iron boasts more strength and flexibility than gray iron while also featuring impact resistance. With a wide range of properties, ductile iron can meet your toughest needs.
