Product Definition
Ferro Silicon is an iron alloy composed of iron and silicon, produced by electric furnace smelting using silica, coke, and iron ore as raw materials. It is widely used as a deoxidizer, alloying agent, and inoculant in the steelmaking and casting industries.
Available Grades (by silicon content)
| Grade | Si Content | Impurities (Fe, Al, Ca, P, S) | Application |
|---|---|---|---|
| FeSi 75 | 75% min | Low | Steel deoxidation, alloying |
| FeSi 72 | 72% min | Standard | General casting, inoculant |
| FeSi 70 | 70% min | Standard | Low-cost alternative |
| FeSi 65 | 65% min | High tolerance | Bulk ferroalloy production |
Other grades (FeSi 45, FeSi 50) available upon request.
Key Features
High silicon recovery – Improves mechanical properties of steel (strength, hardness, elasticity)
Effective deoxidation – Removes oxygen from molten steel, reducing porosity and inclusions
Customizable sizing – Available in lumps (10–100 mm), granules (1–10 mm), or powder (≤1 mm) as per customer requirement
Stable quality – Produced under ISO 9001:2025 control, with SGS/BV inspection before shipment
Typical Applications
Steelmaking – As a deoxidizer and alloying agent for carbon steel, stainless steel, and electrical steel
Foundry – As inoculant for ductile and gray cast iron production
Ferroalloy industry – Raw material for producing other alloys (e.g., magnesium ferrosilicon)
