The main grades of ferrosilicon (FeSi) are classified primarily by silicon (Si) content, because silicon percentage determines deoxidation strength, alloying efficiency, cost, and application suitability in steelmaking and foundry operations.
Below is a steel-industry–focused overview of the grades that are actually used in practice.

Key characteristics
Typical applications
| Grade | Si Content | Main Use | Deoxidation Strength | Cost Efficiency |
|---|---|---|---|---|
| FeSi 75 | ~75% | High-quality steel | Very high | High |
| FeSi 72 | ~72% | General steel | High | Very high |
| FeSi 65 | ~65% | Steel & foundry | Medium | Excellent |
| FeSi 45 | ~45% | Cast iron | Low | Moderate |
Steel plants select FeSi grade based on:
The main grades of ferrosilicon are:
Each grade serves a distinct metallurgical purpose, and they are not interchangeable in professional steelmaking.
