Cast Iron: 

Grey iron is made when pig iron is melted in small cupola furnaces and poured into moulds to make castings. Containing around 2% - 6% carbon, scrap iron or steel is often added to vary the composition. Ductile iron is produced by adding magnesium to the molten pig iron; when the iron is cast, the carbon forms tiny spherical graphite nodules around the magnesium.
