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, sizes and amount of graphite flakes, and the matrix structure. These factories 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 sensitivity, high thermal conductivity, moderate resistance of thermal stock , and outstanding capability.
Shanxi Qinghui Machinery Manufacturer Co.,LTD.has many years of experiences to produce grey iron casting or gray cast iron. All of these grey casting are used in the automobile industry: gear box body, pipeline system and so on. The normal material of grey cast iron is the following: GG15, GG20, GG25.
