With an annual production capacity of 150,000 MT and a team of 300+ professionals, we tailor solutions to meet diverse industrial needs. Below, we break down the chemical compositions and applications of popular grades to help you identify the ideal fit for your projects.
Grade 441 (Si ≥ 99%, Fe ≤ 0.4%, Al ≤ 0.4%, Ca ≤ 0.1%)
Grade 441 balances purity and cost-effectiveness. Its controlled iron (Fe) and aluminum (Al) content make it a top choice for aluminum alloy production, enhancing strength and corrosion resistance. It's also widely used in chemical silicones and solar panel manufacturing due to its consistent reactivity.
Grade 553 (Si ≥ 98.5%, Fe ≤ 0.5%, Al ≤ 0.5%, Ca ≤ 0.3%)
This grade offers slightly higher impurity tolerance, optimizing costs for applications where ultra-high purity isn't critical. It's commonly used in foundry alloys for automotive parts and organic silicon polymers like sealants and lubricants. Its robust thermal stability also suits refractory materials.
Grade 3303 (Si ≥ 99.3%, Fe ≤ 0.3%, Al ≤ 0.3%, Ca ≤ 0.03%)
With ultra-low trace elements, Grade 3303 meets stringent demands for high-tech industries. Its exceptional purity makes it ideal for semiconductor manufacturing, photovoltaic cells, and electronic components, where even minor impurities can impact performance.
