a difficult, brittle, nonmalleable iron-carbon alloy, cast into shape, containing 2 to 4.5 percent carbon, 0.5 to 3 per cent silicon, and lesser quantities of sulfur, manganese, and phosphorus.
A hard and brittle, but powerful, alloy of iron, carbon, and silicon, formed by casting in a mould.
an impure variety of metal, containing from three to six per cent of carbon, element of which will be united with an integral part of the metal, as a carbide, together with remainder is uncombined, as graphite. It there is certainly small free carbon, the item is white iron; if much of the carbon has separated as graphite, it really is known as grey metal. See in addition Cast iron, in the Vocabulary.
an alloy of iron containing much carbon that it's brittle and so can't be wrought but needs to be formed by casting
definitely carbonized iron, the direct item of the blast furnace; -- useful for making castings, as well as for conversion into wrought-iron and steel. It could not be welded or forged, is brittle, and often very difficult. Besides carbon, it contains sulphur, phosphorus, silica, etc.
