Ferro Silicon 65
what is ferro silicon 65?
Ferro (Fe) and silicon (Si) make up the majority of Ferro Silicon 65 (FeSi 65), a ferroalloy with a silicon concentration of roughly 65%. Because of its alloying and deoxidizing qualities, it is extensively utilized in the foundry and steelmaking sectors.
Chemical Composition:
| Element | Content (%) |
| Silicon (Si) | 65% ± 1% |
| Aluminum (Al) | ≤ 2.0% |
| Carbon (C) | ≤ 0.2% |
| Sulfur (S) | ≤ 0.02% |
| Phosphorus(P) | ≤ 0.04% |
| Iron (Fe) | Balance |
Sizes and Forms
- Lumps: 10-80mm,10–100mm, or customized
- Granules: 3–10mm
- Powder: 0-3mm, 1-3mm, 200mesh (used in cored wire or as a raw material)

Features of Ferro Silicon 65
Ferro Silicon 65 Efficient Deoxidizer's features include removing oxygen from molten steel to enhance its quality.
An alloying agent that is less expensive than pure silicon is used to add silicon to steel.
Enhances Mechanical Properties: Steel's strength, hardness, and magnetic qualities are improved.
Consistency in industrial operations is ensured by stable chemical performance.
