Grey Iron Casting

Grey cast iron also known as flake graphite cast iron, is a type of casting iron in which most of the carbon is present as flake graphite .The properties of grey cast iron depends on the distribution, sizs and amount of graphite flakes, and the matrix structure. Casting quality are influenced mainly by the manufacturing conditions, chemical composition, solidification time and rate of cooling in the mould. Grey cast iron exhibits low to moderate strength, low modulus of elasticity, low notch sensitiviy, high thermal conductivity, moderate resistance of thermal stock , and outstanding castability. It is used for housings where tensile strength is non-critical, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative castings. Grey cast iron's high thermal conductivity and specific heat capacity are often exploited to make cast iron cookware and disc brake rotors
