Ferro Silicon

Ferrosilicon is an iron alloy composed of iron and silicon, commonly used as a deoxidizer in steelmaking, and is an important alloy variety in the smelting industry

Specification (Size):

Size: 1-30mm, 1-3mm etc. or as the customer's request.


Block or granular


Silver gray or black


Ferro silicon is often used as a deoxidizer in steelmaking, and because SiO2 is generated by releasing a lot of heat, it is also beneficial for increasing the temperature of molten steel during deoxidation. At the same time, ferrosilicon can also be used as an alloying element additives and is widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Ferrosilicon is commonly used as a reducing agent in ferroalloy production and chemical industry.

The Ferro Silicon Price fluctuates based on several factors, including supply and demand dynamics, raw material costs, production rates, and geopolitical events. Economic conditions and industry trends also play significant roles in influencing the Ferro Silicon Price.
