   1. chem. the most common and most useful metallic element,
      being of almost universal occurrence, usually in the form
      of an oxide as hematite, magnetite, etc., or a hydrous
      oxide as limonite, turgite, etc.. it is reduced on an
      enormous scale in three principal forms; viz., cast
      iron, steel, and wrought iron. iron usually appears
      dark brown, from oxidation or impurity, but when pure, or
      on a fresh surface, is a gray or white metal. it is easily
      oxidized rusted by moisture, and is attacked by many
      corrosive agents. symbol fe latin ferrum. atomic number
      26, atomic weight 55.847. specific gravity, pure iron,
      7.86; cast iron, 7.1. in magnetic properties, it is
      superior to all other substances.

   note: the value of iron is largely due to the facility with
         which it can be worked. thus, when heated it is
         malleable and ductile, and can be easily welded and
         forged at a high temperature. as cast iron, it is
         easily fusible; as steel, is very tough, and when
         tempered very hard and elastic. chemically, iron is
         grouped with cobalt and nickel. steel is a variety of
         iron containing more carbon than wrought iron, but less
         that cast iron. it is made either from wrought iron, by
         roasting in a packing of carbon cementation or from
         cast iron, by burning off the impurities in a bessemer
         converter then called bessemer steel, or directly
         from the iron ore as in the siemens rotatory and
         generating furnace.

   cast iron metal., an impure variety of iron, containing
      from three to six percent of carbon, part of which is
      united with a part of the iron, as a carbide, and the rest
      is uncombined, as graphite. it there is little free
      carbon, the product is white iron; if much of the carbon
      has separated as graphite, it is called gray iron. see

   malleable iron metal., iron sufficiently pure or soft to
      be capable of extension under the hammer; also, specif., a
      kind of iron produced by removing a portion of the carbon
      or other impurities from cast iron, rendering it less
      brittle, and to some extent malleable.

   meteoric iron chem., iron forming a large, and often the
      chief, ingredient of meteorites. it invariably contains a
      small amount of nickel and cobalt. cf. meteorite.

   wrought iron metal., the purest form of iron commonly
      known in the arts, containing only about half of one per
      cent of carbon. it is made either directly from the ore,
      as in the catalan forge or bloomery, or by purifying
      puddling cast iron in a reverberatory furnace or
      refinery. it is tough, malleable, and ductile. when formed
      into bars, it is called bar iron.
