General Introduction to Casting

Metal casting is the manufacturing method in which a metal or an alloy is melted, poured into a mold, and allowed to solidify. Typical uses of castings include municipal hardware, water distribution systems (pipes, pumps, and valves), automotive components (engine blocks, brakes, steering and suspension components, etc.), prosthetics, and gas turbine engine hardware. This introduction explains the steps involved in making a casting using a simplified flow diagram, and discusses the ferrous and nonferrous alloys used for metal casting.
