The characteristics of gray cast iron parts: wear resistance and good shock resistance, because of graphite in the cast ironis conducive to lubrication and oil storage, so good wear resistance. Similarly, due to the existence of graphite, the shockresistance of gray cast iron is better than that of steel. Process performance is good, because of the high carbon content ofthe gray cast iron, close to the eutectic composition, so relatively low melting point, good fluidity, shrinkage of small, so it issuitable for casting of complicated structure or thin-walled castings, the graphite machining easy formation of chip breaking,so grey cast iron can machinability is superior to that of steel.
