Fe-Si Alloy - Overview
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.

Features of Fe-Si Alloy
Versatility
FeSi alloys characterized by high silicon content are used in steel manufacturing. Low-silicon alloys, on the other hand, are preferred in foundries.
Great Deoxidization
The alloy is a key deoxidizing agent in steel and aluminum production.
Enhanced mechanical properties
FeSi improves iron quality and enhances the mechanical properties of aluminum products.
High strength
The silicon helps enhance the strength of steels.
Radiation shielding
Ferrosilicon formulations characterized by high density are effectively used in heavy concrete. The concrete offers radiation shielding. This is particularly useful in construction and nuclear power industries.
Types of FeSi
FeSi, also known as ferrosilicon, is a widely used alloy. It's made primarily of iron and silicon. The silicon content usually ranges from 15% to 90%. When the silicon level increases, the alloy becomes a better material for reducing the weight of steel. It also makes steel more newtonically resistant.
Ferrosilicon is available in different grades and types. They include:
Ferrosilicon 75%
This is one of the most popular types of ferrosilicon alloy. It contains 75% silicon and 25% iron. It's mostly used to produce steel with a high level of silicon content.
Ferrosilicon 15%
This type contains only 15% silicon and 85% iron. It's widely used as a deoxidizer in steel manufacturing.
Medium ferrosilicon
The medium ferrosilicon grade usually contains 25% to 50% silicon. It can be used for different types of steel and iron alloys. They include engineering and construction materials.
Microsilica
Also known as silica fume, microsilica is a by-product of producing ferrosilicon and other silicon alloys. It consists of ultra-fine silicon dioxide particles.
Application of Fe-Si Alloy
Metallurgical
In the metallurgical industry, it is mainly used for steelmaking deoxidation, improving the quality of steel and reducing the loss of chromium oxide. It can also be used as a fuel to reduce energy costs.
Steelmaking
It is used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer for steelmaking for precipitation and diffusion deoxidation.
