Iron Powder

Iron powder is the iron metal discrete particle swarm with particle size less than 1mm. It is an important raw material for powder metallurgy. Industrial production and application of iron powder (Fig. 1) started in the 1920s. Back then, electrolysis process and carbonyl process were used to produce iron powder in Germany. In 1936, Hoeganaes AB of Sweden produced iron powder with low cost by using reduction of magnetite concentrate powder. In the 1940s, Germany, the UK, and the United States produced iron powder by using molten metal atomization process. On this basis, production of atomized prealloyed powders (alloy steel, superalloy, etc.) were quickly advanced. In 1958, China started develo** the reduced iron powder production technology. In the 1960s, the atomization process was used for the production of alloy steel powders and various other alloy powders.
