Ferro Silicon 75-77% Si (10-50 mm)
FeSi 75-77% Low-Aluminium is a premium ferrosilicon grade built for steelmakers who can't afford inclusions. With silicon running 75-77% and aluminium held under 0.01%, it deoxidizes clean and alloys evenly — the kind of consistency mills look for in transformer steel, stainless steel and tool steel production. Manufactured in Armenia and shipped worldwide under the Eurasia brand, every batch ships with full ISO and ASTM certification.
- Si: 75-77%
- Al: ≤ 0.01%
- Size Range: 10-50 mm
- Packing: 1 MT Jumbo Bag

Product Overview
Our FeSi 75-77% Low-Aluminium alloy comes out of controlled-atmosphere reduction furnaces in Armenia, where tight process control keeps aluminium pickup below 0.01% — a level that matters once you're running high-cleanliness steel grades and can't tolerate stray inclusions.
At 75-77% silicon, this grade gives you strong, predictable deoxidation without the higher aluminium content standard FeSi carries. That means fewer inclusions, better hot workability, and more consistent mechanical properties downstream.
We ship factory-direct from Armenia under the Eurasia brand, with COAs, COO certificates and full documentation ready for customs and QC on your end.
Quality You Can Trust
Every batch goes through chemical analysis, sizing and packing checks before it leaves the plant. For steelmakers running FeSi 75-77 in high-purity applications, that traceability isn't optional — it's why our regular buyers keep coming back.
Reliable Global Logistics
We load direct from Bandar Abbas and Imam Khomeini ports for fast transit to Turkey, Qatar, India and beyond. Most orders go out within 7–10 days of payment confirmation, with no waiting on production queues.
High-Purity Alloy Control
Furnace parameters are tuned specifically for the 75-77% Si / ≤0.01% Al window, so you're getting a batch controlled from the melt — not a standard FeSi lot with the aluminium spec relaxed after the fact.

Frequently Asked Questions
What is the main advantage of low-aluminium Ferro Silicon?
It cuts down on inclusions in the finished steel and improves mechanical properties — which is exactly why it's specified for transformer steel, stainless steel and other high-purity grades.
How fast can you ship internationally?
Standard dispatch is 3–5 days after order confirmation. Sea transit runs roughly 10–20 days to Europe and 20–30 days to Asia; rail and road routes to neighboring markets are faster.
Do you offer bulk discounts?
Yes — orders above 500 MT qualify for special pricing and priority shipping slots.
What payment methods are accepted?
T/T, irrevocable L/C at sight, and secure international trade platforms.
Can you customize packaging?
Yes — from standard 1 MT jumbo bags to sealed drums or custom labelling, depending on what your import process needs.
Conclusion
Choosing our Low-Aluminium Ferro Silicon means investing in cleaner steel and fewer headaches downstream. Production out of Armenia, backed by Eurasia's export network, gets you consistent quality without the wait.
Transparent pricing and dependable logistics are why steelmakers and foundries keep coming back to us as their FeSi 75-77% supplier.
