Since alloying leads to improved properties compared to pure metal, pure metal is used less in industry today. In order to prepare the alloy, the pure metal is combined with master alloy. Master alloys are used to deoxygenate, refine grain, improve mechanical properties, increase corrosion resistance, etc. According to the intended application and alloy, different master alloys are used. In general, ferro silicomanganese, ferro silico magnesium, ferrosilicon calcium, ferrosilicon, ferromanganese, ferrophosphorus, ferrochromium, etc. are alloy compounds with different percentages of elements.
