Why the grey iron casting is popular?

The popularity of grey cast iron components is because grey iron is one of the cheapest types of iron castings to produce.  It has acceptable ductility, tensile strength, yield strength, and impact resistance for most applications.  Grey Iron is also excellent in its ability to dampen vibrations making it ideal for machinery bases and as well as many housing applications.  Grey iron has high thermal conductivity meaning it moves heat more easily through the metal.

 

A final benefit of grey iron is its ability to withstand thermal cycling well.  Thermal cycling is where the component goes back and forth between warmer and colder temperatures.  While thermal cycling can create stress and premature failure in some types of metal castings, grey iron has proven to endure the strain of thermal cycling quite well and not stress as easily.

 

While grey cast iron has less tensile strength and shock resistance than most other castings or even steal, it has compressive strength that is comparable to low- and medium-carbon steel. These mechanical properties are controlled by the size and shape of the graphite flakes present in the microstructure.
