Cast iron is iron or a ferrous alloy which has been heated until it liquefies, and is then poured into a mould to solidify. It is usually made from pig iron. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through. Grey cast iron has graphite flakes which deflect a...

Iron (Fe) that has been smelted from a blast furnace to temperatures so high that the ironstone has passed its melting point (15400C) that it has turned to liquid. It contains some carbon from the fuel used. Whilst at temperature it can be run into moulds called pigs for transportation to a foundry. This is brittle. It may be made into steel throu...

Iron with a high Carbon content (above 2%). Identical, in most cases, to Pig Iron, it is easily cast to almost any shape and melts at a lower temperature to other type of iron and steel. Traditionally melted in a Cupular Furnace (a tall cylindrical structure but much smaller than a Blast Furnace).

Cheap but invaluable constructional material, most commonly used for car engine blocks. Cast iron is partly refined pig (crude) iron, which is very fluid when molten and highly suitable for shaping by casting; it contains too many impurities (for example, carbon) to be readily shaped in any other way. Solid cast iron is heavy and can absorb gre...
