Iron that is almost pure (less than 0.15% carbon). Can be shaped and forge welded with ease, but is soft and does not harden in the same way as steel. Wrought iron is rarely seen in molten from as it has a high melting point and there is no advantage in melting it as part of a process. Part of the properties of wrought iron are attributed to the slag inclusions that result from puddling and forge welding. Widely used in bridges, axles and ships plates before the development of Bessemer and Siemens Steel. The last commercial production of wrought Iron in the U.K. ceased in 1976
