Silicomanganese (SiMn), a ferroalloy produced by smelting manganese ore and quartzite in the presence of coke in a submerged arc furnace. SiMn is used as both deoxidizer and for chemistry adjustment of silicon and manganese in iron and steel.

Ferromanganese (FeMn), a ferroalloy produced by smelting manganese ore in the presence of coke. FeMn can be produced in either a blast furnace or a submerged arc furnace. Ferromanganese is typically produced as High Carbon (78% Mn, 7.5% C), Medium Carbon (80% Mn, 1.5% C) and Low Carbon (80% Mn, 0.5% C).  Ferromanganese is used as a strengthener in steel, or in combination with ferrosilicon as a deoxidizer.

Ferrosilicon (FeSi) is a ferroalloy produced by smelting quartzite with coke in presence of scrap iron or iron oxide in a submerged arc furnace.  Identified by the amount of silicon contained, the most common varieties of ferrosilicon produced are 50%, 65% and 75%.  FeSi can contain 1%-2% of calcium and aluminum with the balance of the product made up as iron.  Ferrosilicon is used primarily as a deoxidizer. It readily combines with the oxygen in the molten metal.  It is sometimes used as a degasifier because of its affinity for undesirable gases.  FeSi is also commonly used as a source of silicon in cast iron.  Ferrosilicon can be alloyed with additional metals in custom combinations for specialty uses in steel and iron industries.

Noduloys are ferrosilicon based alloys that converts carbon flakes to spherical shapes called nodules.  It is that transformation that converts grey iron to ductile iron.  Noduloys contains varying levels of magnesium, calcium, aluminum and lanthanides dependent on the customer’s needs.

Inoculants are ferrosilicon based alloys which are used to facilitate desired grain structures and evenly distribute graphitic particles in both grey iron and ductile iron.  Inoculants can contain many different combinations of metals.
