High Purity Ferrosilicon (W-GCFeSi)
What is High Purity Ferrosilicon??
Cost-Effective Ferrosilicon for Bulk Steelmaking | Reliable & Versatile
High Purity Ferrosilicon (W-GCFeSi) is a premium ferroalloy with 75-80% silicon content and exceptionally low impurities (C≤0.012%, S≤0.004%, Al≤0.30%). Designed for critical applications, it delivers superior deoxidation, alloying efficiency, and metal cleanliness in specialty steel, electronics, and aerospace industries.
W-GCFeSi ferrosilicon, ultra-low carbon FeSi, high-purity silicon alloy, semiconductor-grade ferroalloy.
Product Advantages
Unmatched Purity:
12+ elements controlled (e.g., Ti≤0.010%, Nb≤0.010%) for cleaner, stronger metals.
Energy Efficient
Reduces slag formation and smelting energy by 15-20%.
Precision Sizing
Strictly graded 5-30mm blocks minimize fines and optimize melting.
Custom Chemistry
Tailored compositions for specialized needs.
Eco-Compliant
Exceeds RoHS/REACH standards.
low-sulfur ferrosilicon, high-efficiency deoxidizer, energy-saving steel additive.

Production Process
Our W-GCFeSi is crafted through:
Raw Material Selection: High-purity quartz (SiO₂>99%) + low-ash coke.
Submerged Arc Furnace Smelting: Controlled reduction at 1800-2200°C.
Triple Refining:
Slag Refining: Removes Al/Ti using CaO-MgO slag.
Gas Purge: Argon injection to reduce C/S.
Vacuum Treatment: Lowers trace elements (Nb/V/Sb).
Sizing & Grading: Precision crushing + AI-powered size sorting.
Keywords: triple-refined ferrosilicon, low-trace-element production, vacuum-treated FeSi.

FAQs-Clarity in Every Query
Q: What's the lead time for 20-ton orders?
A: 7-15 days after deposit confirmation.
Q: Can I request Nb≤0.005% for nuclear applications?
A: Yes! Custom ultra-low trace element grades available.
Q: Why is 5-30mm size optimal?
A: Ensures rapid melting + minimal oxidation vs. powders.
Q: Are free samples provided?
A: Yes, for verified business partners.
Q: What's the MOQ?
A: 25 tons, with volume discounts.
Q: How do you maintain ≤0.004% sulfur?
A: Through desulfurization slag + argon purging.
Q: Is this suitable for vacuum induction furnaces?
