High Purity Silicon Metal 3303 Lump
High-Performance Silicon Metal 3303 Lumps
Silicon Metal 3303 represents the optimal balance between high purity and cost-efficiency. ZhenAn's Grade 3303 is favored for its strict control of Iron (Fe ≤ 0.3%) and Aluminum (Al ≤ 0.3%), making it the premier choice for specialized alloys and silicone intermediates.
Detailed Specifications
Our refining process ensures that every batch meets the most demanding industrial standards.

FAQ
Q1: Is Silicon Metal 3303 suitable for aluminum alloy wheel production?
A1: Absolutely. Grade 3303 controls both Iron and Aluminum below 0.3%, significantly reducing pores and cracks in castings while improving tensile strength.We supply top-tier automotive component manufacturers; click "Send Inquiry" to request our specialized specs for the automotive sector.
Q2: How do you guarantee the low Calcium (Ca) levels in Grade 3303?
A2: Our process involves precision vacuum slagging to keep Calcium steadily below 0.03%, with some batches reaching as low as 0.01%.This is critical for silicone synthesis. We can send you this week's latest SGS batch report for your reference.
Q3: What is the price advantage of 3303 compared to Grade 441?
A3: While maintaining 99% purity, Grade 3303 offers a more competitive FOB price as its Fe/Al limits are slightly wider than 441.According to March 2nd quotes, 3303 is in a high-value range. Contact us for the latest bottom price.
Q4: Do you have ready stock at Huangpu Port?
A4: Yes, we maintain a regular inventory of standard 3303 lumps, allowing for shipment within 7-15 days after deposit.
