Iron overview :
　One of the most important industrial powder metallurgy metal powder. The maximum amount of iron in powder metallurgy production, which accounts for about 85% of the consumption of the total consumption of the metal powder . The main market is the manufacture of mechanical parts iron , which accounts for about 80% of the required amount of iron in iron production .
　Iron production method, atomizing method is the reduction and the main production methods. Both methods of production capacity in the world 's total production capacity of iron about half and half . Electrolysis and carbonyl method is mainly used for the production of high purity required for magnetic materials , with little fine-grained iron production .

Iron History:
　Iron industrial preparation and application began in the 1920s . At that time the German production of electrolytic iron and carbonyl iron powder , mainly used as a catalyst in the chemical industry . 1930s began producing iron-based powder metallurgy parts . 1933 German production of iron grinding method developed vortex . 1936 Sweden -based sponge iron produced by the reduction of the use of low-cost production of magnetite iron . After 40 years in Germany, Britain and the United States appeared molten metal atomization manufacturing iron , and on this basis, the rapid advance of the pre- atomized alloy ( alloy steel , super alloys, etc. ) powder production . China began in 1958 with the reduced iron , 1960s atomization method developed by various alloy and alloy powder.
