These allowances vary with the type of metal and size of casting. Typical allowances for cast iron are 1/10 to 5/32 in/ft; for steel, 1/8 to 1.4 in/ft; and for aluminum, 1/16 to 5/32 in/ft. These allowances also include a size tolerance for the process so that the casting is dimensionally correct.

Gray Iron Abstract: Cast irons are alloys of iron, carbon, and silicon in which more carbon is present than can be retained in solid solution in austenite at the eutectic temperature. In gray cast iron, the carbon that exceeds the solubility in austenite precipitates as flake graphite. Gray irons usually contain 2.5 to

The casting process involves ductile iron (iron alloys having controlled microstructures) and melting process, plus the use of one of the elements (like magnesium, yttrium or cerium) making it quite ductile. Ductile iron castings, when compared to grey iron castings, have a greater tensile strength and increased ductility.

Compared to nodular cast iron, its casting quality is better, and it is comparable to that of gray cast iron. Its strength is comparable to nodular iron and it has similar anti-vibration properties, thermal conductivity, and casting performance as gray iron. However, it has better plasticity and fatigue resistance than gray iron.

Casting Process. The general premise of casting is putting a melted material into a mold, waiting for it to set, and then taking it out when it's ready. There are, of course, a few extra steps to the process, which can be different for each casting type. In sand casting, the mold pattern is put in the sand mixture until it hardens to make the ...
