ferro alloys

Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese, aluminium, or silicon.[1] They are used in the production of steels and alloys.[2][3] The alloy impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the leading consumer of ferroalloys. The leading ferroalloy-producing countries in 2008 were Ukraine, China, South Africa and Russia, which accounted for 77% of the world production. World production of bulk chromium, manganese and silicon ferroalloys was estimated as 29.1 million tonnes (Mt) in 2008, a 3% decrease compared with 2007.[2]


The main ferroalloys are:


FeAl  C ferroaluminum


FeB  C ferroboron  C 12 C20% of boron, max. 3% of silicon, max. 2% aluminium, max. 1% of carbon


FeCe  C ferrocerium


FeCr  C ferrochromium


FeMg  C ferromagnesium


FeMn  C ferromanganese


FeMo  C ferromolybdenum  C min. 60% Mo, max. 1% Si, max. 0.5% Cu


FeNb  C ferroniobium, also called ferrocolumbium


FeNi  C ferronickel (and nickel pig iron)


FeP  C ferrophosphorus[fr]


FeSi  C ferrosilicon  C 15 C90% Si


FeSiMg  C ferrosilicon magnesium (with Mg 4 to 25%), also called nodulizer


FeTi  C ferrotitanium  C 10..30 C65..75% Ti, max. 5 C6.5% Al, max. 1 C4% Si


FeU  C ferrouranium


FeV  C ferrovanadium


FeW  C ferrotungsten


SiMn - Silicomanganese
