  • For bulk steelmaking deoxidation: FeSi 65% or FeSi 70% is usually sufficient and cost-effective
  • For ductile iron / nodulizer production: FeSi 72% is preferred due to balanced silicon and controlled aluminum
  • For high-grade / clean steel: FeSi 75% offers lower impurities (Al ≤1.5%) for reduced inclusions
  • For electrical steels (GOES/NOES): High Purity FeSi 76-79% is required, with ultra-low Al, B, Ti, C
  • For maximum silicon with minimum iron: FeSi 85% is ideal

What sizes are available for ferro silicon? Can you customize particle size? +

We supply ferro silicon in multiple size ranges, fully customizable to your process need:

  • Lumps: 10-50mm, 10-100mm, 50-100mm — standard for furnace and ladle addition
  • Granules: 2-15mm, 1-6mm, 3-10mm — for controlled dissolution and injection systems
  • Powder: 0-2mm, -40 mesh, -100 mesh, -200 mesh, -325 mesh — for welding, heavy media separation, and chemical applications

Custom sizes are available upon request. Our ferro silicon lumps (10-50mm) are the most popular for steelmaking.

How to get ferro silicon price? What affects the price? +

Ferro silicon price is influenced by several factors: silicon content grade (FeSi 65/72/75/85), quantity (MT), particle size, impurity requirements, packaging, and delivery terms (FOB/CIF). For the latest ferro silicon price per ton, please submit a quotation request with your specifications. We By email/whatsapp/wechat Reply within 2 hours(M-F 9:00-17:00 GTM+8) with a detailed offer including COA.

What quality certifications do you provide? Is third-party inspection available? +

As a reliable ferro silicon supplier and manufacturer, we provide:

  • Material Test Certificate (COA) — with chemical analysis (Si, Al, C, P, S) for every batch
  • Third-party inspection — SGS, Bureau Veritas (BV), Intertek inspection is welcomed and fully supported before shipment
  • Full material traceability — from raw material to final shipment with batch tracking documentation

Learn more about our quality control system on our Quality Control & Ferroalloy Inspection page.

What size of ferro silicon lumps is best for my application? +

The most commonly used ferro silicon lumps are 10-50 or 10-60mm for standard furnace and ladle addition. For larger furnaces, 10-100mm lumps may be preferred. The optimal size depends on your furnace type, addition method, and target dissolution rate. Contact our technical team for a personalized recommendation based on your steelmaking process.
