Silico Manganese (SiMn) is an alloy with Manganese, Silicon and Iron. It is produced by smelting of Manganese ore with coke and a quartz flux

Ferro Manganese (FeMn) is an alloy with high percentage of manganese, which is made by heating a mixture of oxides, MnO2 and Fe2O3

Ferrosilicon (FeSi) is an alloy of iron and silicon with a very variable silicon content between 70% and 75%. It is used as a so-called master alloy in steel production
