Ferrosilicon (also written as ferro silicon, ferro silica, ferro silicium, ferrosilicio, or silicon ferro) is a ferroalloy composed primarily of iron (Fe) and silicon (Si), commonly referred to as FeSi ferrosilicon.
Ferrosilicon is widely used as:
Its high silicon content improves strength, magnetic properties, corrosion resistance, and metallurgical control during melting.
Common grades:
| Element | Typical Percentage |
| Silicon (Si) | 70–75% |
| Aluminum (Al) | ≤ 2% |
| Carbon (C) | ≤ 0.25% |
| Other elements | Trace amounts |
Each shipment is supplied with ferro silicon chemical analysis and ferro silicon composition percentage documentation.
Common uses of ferro silicon include:
These ferrosilicon uses make it essential for both steel casting raw material and cast iron raw material applications.
Ferrosilicon is produced in electric arc furnaces using high-purity silica and iron sources.
Key ferro silicon properties include:
