WebGrey Iron FGL200 in France standard NF A32-101 is a type of cast iron that has a graphite microstructure. Below are the chemical composition and physical properties of this material. It is named after the grey color of the fracture it forms, which is due to the presence of graphite. It is the most common cast iron and the most widely used cast ... WebAs a result, the properties of CGI fall between grey cast iron and nodular cast iron. The tensile strength of CGI is 1.5 to 2 times higher than that of grey cast iron, and, the modulus of CGI is 150 GPa compared to 105 GPa for grey cast iron. The thermal conductivity of CGI is lower: 38 W/m-°K compared to 48 W/m-°K for grey cast iron. With ...
