Grey iron base have excellent mechanical and physical properties with different strength, hardness, toughness with comprehensive performance and also have some special features. Such as resistance, high and low temperature resistance, corrosion resistance.
Features of grey iron:
1.High performance on abrasive resistance and shock absorption. Graphite have good capacity on lubrication and oil storage, so the abrasive resistance is good. Similarly, due to the graphite, shock absorption of grey iron is better than steel and others.
2.Process performance. Due to the high carbon content of gray cast iron, It is close to eutectic composition, so low melting point, good fluidity, small shrinkage , so it is suitable for casting complicate structure or thin wall castings. In addition, the graphite grey iron is easy to be cut.
