Ferro Alloys

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. They are used in the production of steels and alloys. 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 main ferroalloys are:

  • FeAl – ferroaluminum
  • FeB – ferroboron – 12–20% of boron, max. 3% of silicon, max. 2% aluminium, max. 1% of carbon
  • FeCe – ferrocerium
  • FeCr – ferrochromium
  • FeMg – ferromagnesium
  • FeMn – ferromanganese
  • FeMo – ferromolybdenum – min. 60% Mo, max. 1% Si, max. 0.5% Cu
  • FeNb – ferroniobium, also called ferrocolumbium
  • FeNi – ferronickel (and nickel pig iron)
  • FeP – ferrophosphorus[fr]
  • FeSi – ferrosilicon – 15–90% Si
  • FeSiMg – ferrosilicon magnesium (with Mg 4 to 25%), also called nodulizer
  • FeTi – ferrotitanium – 10..30–65..75% Ti, max. 5–6.5% Al, max. 1–4% Si
  • FeU – ferrouranium
  • FeV – ferrovanadium
  • FeW – ferrotungsten
  • SiMn - Silicomanganese
