WebGray cast iron is a broad term used for a number of cast irons whose microstructure is characterized by the presence of flake graphite in the ferrous matrix. Such castings often contain 2.5%–4% carbon, 1%–3% silicon, and some additions of manganese ranging from 0.1% to 1.2%. This is one of the most widely used alloys of iron. WebFerrous structural metals, cast iron, wrought iron and steel, are alloys of iron, carbon and other impurities, the most common of which is silicon. Pure iron is soft and weak and has no commercial application. During the Industrial Revolution, iron was extracted from iron ore (usually an iron oxide) by smelting.
