Cast Iron
Gray Cast Iron
Gray iron is a hard brittle material with excellent damping characteristics and good machinability. This is due to graphite flakes which precipitate into the iron during solidification. Gray iron is a great thermal conductor with great wear resistance that absorbs vibration. Common applications are bushings, gears, pulleys and rollers.

Ductile Cast Iron
Ductile Iron is a unique alloy that is similar to gray iron except that it is not brittle and is able to flex with more fatigue resistance than gray iron. These properties are a result of creating graphite nodules instead of graphite flakes during solidification. Ductile iron is light and absorbs vibration.
