Ferrosilicon is primarily used as an additive in the production of steel and cast iron. It is also used as a deoxidizer and inoculant in the production of nonferrous metals, such as aluminum and copper.
Ferrosilicon is added to steel to improve its strength and hardness, as well as to reduce its susceptibility to corrosion. It also helps to deoxidize the steel, which improves its quality and workability.
The price of ferrosilicon varies depending on factors such as global supply and demand, production costs, and market conditions. As of March 2023, the price of ferrosilicon is around $1,000 - $1,500 per metric ton.
