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. 

GAA offers two grades of silicomanganese, Regular SiMn (Mn 65%) and High Grade SiMn (Mn 72%). Customized sizing available upon request.
