441 Silicon Metal Lumps

441 Silicon Metal Lumps are high-purity industrial silicon products with a silicon (Si) content of ≥99.1%, primarily composed of high-purity silicon and trace impurities including iron (Fe), aluminum (Al), calcium (Ca), and phosphorus (P). The "441" grade follows industry grading standards, representing maximum impurity percentages of Fe≤0.4%, Al≤0.4%, and Ca≤0.1%, ensuring excellent performance in high-tech and industrial scenarios. Available in lump, powder, or particle forms, with customizable sizes such as 0~1mm, 1~3mm, 10~50mm, 10~60mm, 10~100mm, 40~120 mesh, 45~325 mesh, etc., it is packaged in 25kg/bag, 1-ton bags, or customized per customer requirements. Widely used in metallurgy, electronics, new energy, chemicals, and casting industries, it delivers reliable stability and functionality.

1. Semiconductor industry

High-purity silicon metal (such as metal silicon 441 with a silicon content of 99.1%) can be used to manufacture semiconductor silicon wafers after further refining, and is widely used in electronic components, integrated circuits (ICs), photovoltaic solar cells and other fields.

2. Photovoltaic industry

Silicon metal can be converted into high-purity monocrystalline silicon or polycrystalline silicon after refining. These silicon materials are the basis for manufacturing solar panels.

3. Aluminum alloy production

As an alloying element in aluminum alloys, silicon-metal 441 can effectively improve the hardness, strength, fluidity and wear resistance of aluminum alloys, and is widely used in aluminum alloy production in the fields of automobiles, machinery, aviation, etc.

4. Silicon-aluminum alloy production

It is often used in the production of silicon-aluminum alloy. Silicon-aluminum alloy is mainly used to smelt aluminum alloy. Silicon can improve the fluidity, strength and wear resistance of aluminum alloy, especially in applications that require lightweight and high-strength materials.

5. Silicone chemical production

Silicon metal is an important raw material for silicone chemicals (such as silicone rubber, silicone oil, silicone resin, etc.). By reacting with other chemicals, metal silicon can produce various silicone compounds.

6. Foundry industry

It is often used in the production of cast iron. Adding silicon metal to cast iron can improve the fluidity of cast iron, reduce shrinkage and improve the mechanical strength of castings.

7. Power industry

It is also used in the power industry, especially in high temperature environments. Its electrical conductivity and high temperature resistance make it play an important role in the production of power equipment.
