Ferro Silicon 72% 75% for Cast Iron Production Foundry Treatment and Steelmaking Applications

One coordination desk covers both grades, so dual-grade containers, split packing plans and per-grade papers all come out of a single conversation.

Read the two lines side by side: the C, P and S ceilings are shared, while Si and Al are what actually separate the grades.

• Per grade, forms offered: lump 10–50 / 50–100 mm and granules 0–3 / 3–10 mm.
• The 75 can arrive low-Al (Al ≤0.5%) for sensitive ductile iron and clean steels.
• Every grade lot is certified on its own GB/T 2272 aligned papers.

• Base iron silicon correction and graphitization support in cast iron production.
• Foundry treatment: inoculation of gray and ductile iron, grade and size matched to the method.
• Steel shop: deoxidation of the melt and silicon alloying to the grade window.
• Nodulizer base: FeSi 75 as the silicon carrier in FeSiMg production.
• Reductant duties when making low-carbon ferroalloys.

• Split the order line by line — grade, form, size and tonnage for the foundry, and separately for the steel shop.
• Confirm the destination port and whether both grades may share one container.
• Documents: per-grade certificates of analysis, optional SGS or BV inspection.
• Packing per line: jumbo bags for bulk handling, 25 kg moisture-proof bags for the foundry floor.
• Dispatch 5–10 working days from payment; L/C, T/T and Western Union all accepted; 2,000 MT monthly capacity; no fixed MOQ.

1. Line-by-line demand: grade, form, size window and monthly tonnage for each line.
2. The base irons and steel grades you produce.
3. Destination port, and whether one container should carry both grades.
4. Packing preference per line.
