High Class Ferro Silicon Blocks Of Various Sizes

The core product of ZHEN AN is ferrosilicon, a high quality product used as an important raw material in the steel industry. The purity may be specified according to the customer's demand.

Ferrosilicon (FeSi) is an alloy of silicon and iron. Finnfjord's standard ferrosilicon contains 75% silicon and 20-24% iron. The annual production capacity at Finnfjord is 100,000 tonnes. The production is based on quartz, iron ore, coal, coke and biocarbon. The alloy is mainly used as a deoxidant and an alloying element in the production of steel and cast iron. FeSi increases strength, hardness, temperateness and corrosion resistance in steel.

Ferrosilicon (FeSi) is an alloy of iron and silicon that is principally used in steelmaking for deoxidation and as an alloying component. Elkem is one of the largest suppliers of premium-grade ferrosilicon ferroalloys worldwide, and we're ready to help you identify the best product for your application.

How is ferrosilicon made?

Ferrosilicon, commonly abbreviated FeSi, is an iron–silicon alloy that also contains smaller proportions of other elements. The most popular grade of ferrosilicon contains 75 wt% silicon ('FeSi75'), but the amount can range from 15–90 wt% depending on the application.

The highest-quality ferrosilicon is made in an electric arc furnace by reducing silica with coke in the presence of iron (usually derived steel scrap or iron ore). The ferrosilicon usually takes the form of shiny, metallic-grey lumps, but is also available as pre-formed briquettes.
