Grey cast iron derives its name from the gray color of the fracture surface of the material. This gray appearance results from the presence of graphite flakes, which are formed during the solidification process. The microstructure of grey cast iron primarily consists of iron, carbon, and silicon, with carbon content typically ranging from 2.5% to 4%. The presence of graphite in the iron matrix enhances its mechanical properties, including strength and ductility.
