What is the difference between manganese and ferrosilicon? Manganese-silicon alloy is an iron alloy containing more than 65% manganese and less than 27% silicon. It is mainly used in steel production because manganese with silicon can both deoxidize and increase the manganese content of steel, making it stronger, harder, wear-resistant, and easy to weld.
Ferrosilicon is an alloy of iron and silicon, consisting mainly of silicon and iron, with more than 90% silicon in it. It is often used in steel production and in the smelting of other metals.
