Iron is the chemical element with the atomic number 26. Its symbol is Fe (from Latin. From Ferrum).
Electrolysis-purified (99.97% +) iron pieces and a high-purity (99.9999% = 6N) 1 cm3 volume iron cube for comparison.
Iron is the most abundant metal in the earth's crust. Although the liquid core in the center of the earth is also estimated to be a single iron crystal, it is more likely to have an iron nickel alloy. It is believed that such a large amount of dense iron mass in the center of the world affects the magnetic field of the earth.
Iron metal is obtained from iron ores and is rarely found elemental in nature. To obtain metallic iron, impurities in the ore (Indg: impurity) must be removed by chemical reduction. Iron is actually used in steel making, which can be considered a largely carbon alloy.
Iron, together with the carbon when heated to 1420-1470 K temperature resulting liquid melt is an alloy containing 96.5% iron and 3.5% carbon and is called cast iron or pig. This product can be poured into the fine detail, as long as it contains is decarburized to remove most of the carbon is too brittle to be processed.
