FeSi Alloy 72% 75% for Steelmaking Deoxidation Foundry Applications and Alloy Manufacturing

Ferrosilicon is not only a steel shop consumable — it is a feedstock. Plants making FeSiMg nodulizers, low-carbon ferroalloys, or magnesium via the Pidgeon route all start from the same material the ladle burns: FeSi 72 and FeSi 75. That is why ZHENAN runs the two grades as separate, tightly documented streams for three audiences at once. Steel shops take them for deoxidation; foundries for inoculation and silicon addition; alloy manufacturers trust them as a silicon feed with stable lot-to-lot chemistry, because a blending calculation is only as good as the consistency behind it. Aluminium is controlled per grade — ≤2.0% on the 72, ≤1.5% on the 75 (low-Al line ≤0.5%) — and every batch is analysed before release, so whether the lot heads to a ladle, a foundry or a nodulizer blend, the certificate matches the material exactly.

• Producer: ZhenAn
• Base: Anyang, Henan, China
• System: ISO 9001
• Models: FeSi 72 / FeSi 75, in lump and granules
• Consistency pledge: consecutive lots are analysed to the same protocol, so feedstock math stays valid across shipments

FeSi 72 ships at Si ≥72% with Al ≤2.0%, C ≤0.2%, P ≤0.04% and S ≤0.02%. FeSi 75 tightens the silicon floor to ≥75% and the aluminium cap to ≤1.5% while holding the same C, P and S ceilings. For blending calculations, the lot values below are the numbers to use — documented, stable, never blended.

• The 75 grade runs in a low-Al version at Al ≤0.5%.
• Forms: lump 10–50 / 50–100 mm; granules 0–3 / 3–10 mm.
• Certificates per batch and per grade keep the silicon credit stable enough to plan recipes around.

• Deoxidation across EAF, BOF and induction routes — the primary duty of both grades.
• Foundry work: inoculation and silicon addition in gray and ductile iron production.
• Alloy manufacturing: silicon feedstock for FeSiMg and other pre-alloys.
• Magnesium smelting: FeSi 75 as the conventional reductant in Pidgeon-process plants.
• Chemical and electrode products: a silicon source wherever the process specification calls for it.

Before the contract is signed, four things get settled with us:

• The consumption split per audience — ladle, foundry, alloy line — with grade, form and window for each;
• The Si and Al windows your own process requires, so we can match the lot to them;
• Documentation: per-batch, per-grade COA; pre-production sample and final inspection standard, SGS or BV on request;
• Logistics and commercials: 1 MT jumbo or small bags; rolling dispatches 5–10 working days after each payment; L/C, T/T & Western Union; 2,000 MT monthly; no fixed MOQ.

To receive an accurate quotation, please share the following:

• The process each line runs — steelmaking, foundry work, or alloy / magnesium production;
• Grade, form and size window per line;
• The Si and Al windows your process requires;
• Monthly tonnage, destination port and packing preference.
