Gray iron castings are iron alloyed parts produced in foundries, not to be confused with forges, where they are formed via closed mold operations for applications in a wide variety of industries. Industries that grey iron castings serve include agriculture, architecture, automotive, construction, electronics, irrigation, machinery construction, transportation, and ventilation. Grey iron castings lend durability and strength to any operation for which they are used.
To acquire grey iron, metalworkers must first mine iron ores or iron oxides and then process it in a special type of blast furnace, called an electric induction furnace or a cupola. The generally accepted composition of cast grey iron is 95% iron by weight, plus 1 to 3% silicone and 2.1 to 4% carbon. The high amount of silicone, which produces graphite when heated, is the element responsible for grey iron's coloring. It manifests itself when fractures form, revealing its graphitic microstructure. The exact appearance of individual grey iron depends on both temperature and timing. Other than appearance, variable properties of castings include thermal conductivity, energy dissipation, resistance to wear and deformation, and melting point. Additional elements that may appear in grey iron castings, whether intentionally, to alter specific properties, or unintentionally, include manganese and sulfur; the latter is often added into molten iron to increase its hardness. When metalworkers have reached the grey iron mixture they want, they proceed to casting.
