At Beifang Alloy, we specialize in high-purity silicon metal (Si ≥ 98.5%) for industries like aluminum alloys, chemicals, and solar panels. This guide covers procurement needs, market trends, buying strategies, and supplier selection to help you secure the best silicon metal for your operations.
| Application | Required Purity | Critical Impurities |
|---|---|---|
| Aluminum Alloys | 98.5-99.0% Si | Fe < 0.5%, Al < 0.2% |
| Chemical/Silicones | 99.0-99.5% Si | Ca < 0.1%, Ti < 0.05% |
| Solar & Electronics | 99.99%+ Si (4N-6N) | B, P < 1ppm |
✔ Consistency – Batch-to-batch uniformity for stable production
✔ Low Trace Elements – B, P, and Fe must meet strict limits
✔ Sustainability – Energy-efficient production preferred (EU CBAM compliance)
✔ Logistics Reliability – Moisture-proof packaging for long-distance shipping
🔹 Solar Boom – Polysilicon demand up 18% YoY, driving 99.99% Si metal prices
🔹 EV Battery Growth – Silicon anode demand to reach $7B by 2030
🔹 Supply Chain Risks – China dominates supply (75% global production)
✔ Certifications – ISO 9001, REACH, TÜV SÜD
✔ Production Capacity – Minimum 10,000MT/year for stable supply
✔ Testing Methods – GDMS for 4N+ grades, XRF for standard
| Criteria | Beifang Alloy | Industry Standard |
|---|---|---|
| Purity | 98.5%-99.99% (customizable) | 98.5-99.5% |
| Impurity Control | B/P < 5ppm (4N grade) | B/P < 20ppm |
| Production | Hydro-powered ARC furnaces | Coal-based smelting |
| Lead Time | 30 days (FOB China) | 45-60 days |
| Sustainability | 2.3t CO₂/MT (vs industry 3.5t) | Limited carbon reporting |
