Gray Iron Castings

2 sections

Gray iron castings are created by molding molten grey iron. Foundries have cast gray iron for centuries, making it possibly the oldest of all worked metals. It is also the most abundant metal material and one of the least expensive because of its abundance.

Applications of Gray Iron Castings

Gray iron castings are widely used in the automotive, appliance, agricultural, and machinery industries. Gray iron can be found in pump housings, electrical boxes, engine blocks, and decorative castings.

Manufacturing Process of Gray Iron Castings

Gray iron was the original cast iron, although it has recently been replaced in many applications by other iron-carbon alloys with a stronger tensile strength.Gray iron is cast much like any other metal. It is poured into a mold and extracted after it cools. There are several different casting methods through which gray iron is molded, including green sand molding, shell molding, and centrifugal molding. The method by which the gray iron is cast can have an effect on the mechanical properties of the metal, especially in respect to its cooling rate.
