Silicon Metal 411

Silicon is the second most abundant element in the Earth's crust after oxygen, constituting 27.7% of its composition.

Silicon Metal 411(Si 411), also known as industrial silicon grade 411, is a gray and shiny semiconductor metal.

Silicon Metal 411 Composition and Specifications:

Silicon metal grade 411 consists of approximately 99.4% silicon, 0.4% iron, 0.1% aluminum, and 0.1% calcium.

The diameter of silicon metal 411 particles typically ranges from 0-10mm or 10-100mm, depending on client requirements.

• Si metal 411 serves as an additive in non-iron-based alloys.

1. Aluminum Alloys: Adding Si metal 411 to aluminum alloys enhances their strength, anti-oxidation properties, corrosion resistance, and casting performance. It also reduces density and coefficient of thermal expansion.

2. Cold-Rolled Silicon Steel: Si metal 411 improves the magnetic properties of steel, increasing permeability and reducing hysteresis and eddy current losses.

3. High Purity Semiconductor Production: High-purity silicon metal is crucial for manufacturing semiconductor devices, including integrated circuits.

4. Organic Silicon Products:

Silicone: Used for high-temperature gaskets and cold insulation materials.

Silicon Resin: Used in insulating paint and high-temperature coatings.

To ensure the quality of Silicon Metal 411, we have adopted strict quality control measures and are subject to third-party testing.

We commission independent third-party laboratories (e.g. SGS, CCICD, etc.) to test and verify Silicon Metal 411. These laboratories are authoritative and can provide objective and reliable test results.

1. Purity: Ensure that the silicon content meets the required standards.

2. Impurity content: Monitor the content of impurities such as iron, aluminum, calcium, etc. to ensure that it is within the allowable range.

3. Particle size: Check the size distribution of silicon particles to meet customer requirements.

We continue to improve and optimize our production processes to ensure that we provide our customers with stable and reliable high-quality silicon metal 411. While meeting our customers' needs, we maintain cooperation with third-party laboratories to ensure the reliability and transparency of product quality.
