Water colored red by Iron. Iron comprises 95 percent of all the metal tonnage produced worldwide. Its combination of low cost and high strength make it indispensable, especially in applications like automobiles, the hulls of large ships, and structural components for buildings. The first signs of use of iron come from the Sumerians and the Egyptians, where around 4000 BC, small items were being fashioned from iron recovered from meteorites.
