Premium FeSi 45 Lump for Casting is intended for high-volume foundry operations that require dependable silicon correction with controlled cost. With a 45 percent silicon level, this grade supports routine melt conditioning and helps stabilize casting results when the main goal is process consistency rather than high-alloy performance. The lump format (commonly 50–100 mm) delivers strong handling durability and reduces fragmentation during loading, storage, and furnace charging.
For casting lines, the value of FeSi 45 is its practical balance: stable melting behavior, manageable impurity control and reliable supply continuity. When used correctly, it supports repeatable melt response and helps foundries maintain steady production efficiency across long runs.

|---|---|---|
| Silicon (Si) | 45% | Suitable for routine melt correction |
| Aluminum (Al) | ≤ 1.0% | Supports cleaner melt behavior |
| Sulfur (S) | ≤ 0.02% | Reduces melt interference |
| Phosphorus (P) | ≤ 0.04% | Improves casting stability |
| Lump Size | 50–100 mm | Durable handling and charging |
| Packaging | 1000 kg jumbo bags | Moisture-protected shipment |
Q：How do you verify FeSi 45 quality before shipment
A：Each batch is tested for chemical composition, impurity limits and lump integrity to ensure stable casting performance.
Q：What delivery lead time should be planned
A：Typical shipment requires 15–20 days depending on destination port and vessel schedule.
Q：Do you provide support for casting usage
A：Yes, we provide guidance on addition timing, dosage planning and melt adjustment to support consistent foundry results.
