FAQ
Q1: What is the main difference between Silicon Metal 2202 and 553/441 grades?
A: The core difference lies in purity. Grade 2202 requires Iron (Fe) and Aluminum (Al) to be ≤ 0.20%, whereas 553 allows up to 0.50%. 2202 is engineered for high-tech industries like solar PV and semiconductors where impurities must be strictly minimized.If your application is less sensitive, our Silicon Metal 421 might be a more cost-effective option. Contact us for a specification comparison.
Q2: Do you provide Silicon Metal 2202 in powder form?
A: Yes, absolutely. We operate a professional crushing and grinding workshop. In addition to standard 10-100mm lumps, we can process Grade 2202 into silicon metal powder (200 mesh, 325 mesh, etc.) while ensuring the low-impurity profile remains uncontaminated during processing.
Q3: How do you guarantee the Al and Fe levels in every batch of 2202 lumps?
A: ZhenAn maintains a rigorous laboratory testing system. Every batch is sampled twice before leaving the factory, and a Mill Test Certificate (MTC) is provided with each shipment. We also fully support pre-shipment inspections by SGS or BV.
Q4: What is the current FOB Huangpu price for Silicon Metal 2202?
A: Prices for 2202 are influenced by raw material costs and demand from the solar industry. Based on market trends, it carries a premium over metallurgical grades like 553.Our price list is updated every Monday.
