At Beifang Alloy, we specialize in producing high-purity ferrosilicon (FeSi) that significantly improves steel hardness—critical for applications in automotive, tool steel, and wear-resistant alloys. This guide covers procurement needs, market trends, buying strategies, and supplier selection to help you optimize steel hardness with the right FeSi.
| Parameter | Standard Grade | Premium Grade |
|---|---|---|
| Si Content | 65-75% | 72-75% |
| Carbon (C) | ≤0.1% | ≤0.05% |
| Aluminum (Al) | ≤1.5% | ≤0.5% |
| Phosphorus (P) | ≤0.04% | ≤0.02% |
✔ Silicon Solid Solution Strengthening – Enhances matrix hardness
✔ Refines Grain Structure – Improves wear resistance in tool steels
✔ Reduces Brittleness – Balances hardness with toughness
✔ Low Aluminum Content – Al >0.5% can reduce hardenability
✔ Consistent Si% – ±0.3% variation for uniform heat treatment
✔ Traceability – Mill test reports (MTRs) for critical applications
🔹 Automotive Lightweighting – High-strength steel demand up 15% YoY
🔹 Tool Steel Expansion – Global market to reach $6.5B by 2027
🔹 Mining & Cement Growth – Wear-resistant alloys needing high-Si FeSi
✔ Certifications – ISO 9001, ISO 17025 lab accreditation
✔ Testing Capabilities – XRF for Si%, LECO for carbon
✔ Sustainability – CBAM-compliant carbon reporting (<2.5t CO₂/MT)
| Criteria | Beifang Alloy | Industry Average |
