Ferroalloy

From Wikipedia, the free encyclopedia

Ferroalloy refers to various alloys of iron with a high proportion of one or more other element, manganese or silicon for example. It is used in the production of steels and alloys as a raw material.

The main ferroalloys are:

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