This guide explores:
✔ Key procurement needs for foundries
✔ Latest industry trends in silicon metal
✔ Step-by-step procurement guide
✔ How to compare suppliers effectively

1. Procurement Needs for Silicon Metal in Foundries

Foundries rely on silicon metal for:

• Aluminum Alloy Production – Enhances fluidity, castability, and strength.
• Silicones & Chemical Applications – Used in resins, lubricants, and sealants.
• Steel & Iron Casting – Improves deoxidation and heat resistance.
• Photovoltaic & Electronics – Ultra-high purity (99.999%) for solar cells and semiconductors.

Buyer Checklist: Key Requirements

🔹 Purity Grades – Si 98%, 99%, or 99.5% (based on application).
🔹 Low Impurities – Iron (Fe), Aluminum (Al), Calcium (Ca) must be minimized.
🔹 Particle Size – Lumps (10-100mm), granules (1-10mm), or powder (custom).
🔹 Supply Stability – Consistent quality and bulk availability.

2. Industry Research: Silicon Metal Market Trends

Current Market Dynamics

🌍 China Dominates Supply – Produces ~70% of global silicon metal.
🏭 Growing Demand in Solar & EVs – High-purity Si for PV panels and lithium-ion batteries.
⚡ Energy-Intensive Production – Electricity costs significantly impact pricing.

Future Outlook

🔹 Green Energy Boom – Solar industry demand will drive ultra-high-purity silicon.
🔹 Supply Chain Localization – Western buyers diversifying sources due to geopolitical risks.

3. Procurement Guide: How to Choose the Right Silicon Metal

Step 1: Define Technical Specifications

• For Aluminum Foundries → Si 98-99% (low Fe, Ca).
• For Solar/Electronics → Si 99.99%+ (metallurgical or chemical grade).
• For Steel Additives → Si 97-98.5% (cost-effective).

Step 2: Evaluate Supplier Credentials

🔎 Manufacturer vs. Trader – Direct sourcing (like Beifang Alloy) ensures better QC and pricing.
📜 Certifications – ISO, RoHS, or industry-specific compliance.
🏭 Production Capacity – Can they support large orders (500+ MT/month)?

Step 3: Compare Pricing & Logistics

💰 FOB vs. CIF Pricing – Factor in shipping costs.
📦 Packaging – 1-ton bags, customized sizes, or bulk shipments.
⏱ Lead Time – Ensure timely delivery to avoid production delays.

Step 4: Request Samples & Testing

• Verify Si content, impurity levels, and consistency via lab tests.
