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 propertises of grey cast iron depends on the distribution, sizs and amount of graphite flakes, and the matrix structure. These factorys are in turn, influenced mainly by the manufacturing conditions, chemical composition, solidification time and rate of cooling in he mould. Grey cast iron exhibit low to moderate strength, low modulus of elasticity, low notch sensitiviy, high thermal conductivity, moderate resistance of thermal stock , and outstanding castability.

Ductile iron casting as found wide acceptance and competes favourably with steel such that its use in engineering has increased in recent times as while grey cast iron and malleable cast iron has fallen in popularity as other materials such as plastics have found favour.

Ductile iron casting has a clear advantage over malleable iron for applications where low solidification shrinkage is needed or where the section is too thick to permit uniform solidification as white iron

Iron Casting is an alloy of iron and carbon in which the carbon is in excess of the amount that can be retained in solid solution in austenite at the eutectic temperature, In addition, silicon, manganese,sulphur and phosphorus are contained in varying amounts.

Iron Casting are a family of ferrous metals with a wide range of properties produced by being cast into shape as opposed by being formed,other elements are used to control specific properties, cast irons have a wide range of mechanical properties which make them suitable for use in engineering components. The wide spread use of cast iron is as a result of its low cost and versatile properties.
