Metal Silicon Si 3303 Grade Description
Silicon Metal 3303 grade for aluminum alloy production requires Si ≥99.0%, Fe ≤0.3%, Al ≤0.3%, and Ca ≤0.03%. Impurity fluctuation is controlled within ±0.05% per batch. Physical forms consist of 10-100mm natural lumps or 10-50mm crushed lumps. Fines under 10mm are limited to <3% via automated screening. Moisture content is maintained at ≤0.5% through pre-shipment drying. Packaging utilizes double-layer waterproof jumbo bags. A 3,000-ton standing stock is held at the Anyang warehouse. Third-party inspection (SGS/BV) is available at the loading port. Lead time is 7-10 days to Tianjin or Qingdao port.
