Iron is a metal with the greatest technical importance. Its useful physical properties include relatively high hardness, ductility and large malleability, relatively low production costs and high prevalence in nature. However, chemically pure iron has practically no direct use, while iron alloys with carbon, silicon and other metals have an enormous technical and practical importance. 

Soft magnetic materials are characterized by high permeabiUty and low coercivity. There are sis principal groups of commercially important soft magnetic materials iron and low carbon steels, iron—siUcon alloys, iron—aluminum and iron—aluminum—silicon alloys, nickel—iron alloys, iron-cobalt alloys, and ferrites. In addition, iron-boron-based amorphous soft magnetic alloys are commercially available. Some have properties similar to the best grades of the permalloys whereas others exhibit core losses substantially below those of the oriented siUcon steels. Table 1 summarizes the properties of some of these materials. 

The discussion so far has been limited to the structure of pure metals, and to the defects which exist in crysteds comprised of atoms of one element only. In fact, of course, pure metals are comparatively rare and all commercial materials contain impurities and, in many cases also, deliberate alloying additions. In the production of commercially pure metals and of alloys, impurities are inevitably introduced into the metal, e.g. manganese, silicon and phosphorus in mild steel, and iron and silicon in aluminium alloys. However, most commercial materials are not even nominally pure metals but are alloys in which deliberate additions of one or more elements have been made, usually to improve some property of the metal examples are the addition of carbon or nickel and chromium to iron to give, respectively, carbon and stainless steels and the addition of copper to aluminium to give a high-strength age-hardenable alloy. 

CAST IRON. Generic term for a group of metals that basically are alloys of carbon and silicon with iron. Relative to steel, cast irons are high in carbon and silicon, carbon ranging from 0.5 to 4.29F and silicon from... 

In the process of SiCfr preparation the main raw stock is ferrosilicon, an alloy of iron and silicon, made in shaft electric furnaces. Electrothermal ferrosilicon is produced from quartzite and iron chipping it is reduced with charcoal or coke (petroleum or metallurgical). The process is based on the endothermal reaction of silica reduction with carbon, which takes place at high temperature. 

Silicon contaminated with carbon can be obtained by reduction ot silica, SiOs, with carbon in an electric furnace. An alloy of iron and silicon, called ferrosilicon, is obtained by reducing a mixture of iron oxide and silica with carbon.
