Industrial Silicon Metal 441 is an important grade of industrial silicon metal. The "441" in Industrial Silicon Metal 441 is a numbering method that indicates its chemical composition. Among them, the first two "4"s represent that the content of iron (Fe) and aluminum (Al) elements does not exceed 0.4%, and the last "1" represents that the content of calcium (Ca) elements does not exceed 0.1%. The rest is mostly silicon (Si), and the silicon content is usually around 99%.

Industrial Silicon 441 occupies an important position in the global industrial silicon metal market and is one of the silicon metal grades with a large trading volume. Its output and market demand are affected by many factors such as the global economic situation and the development of downstream industries. In international trade, China is one of the main producers and exporters of Industrial Silicon Metal 441, and its products are exported all over the world, providing important basic material support for global industrial production.

Application Field

Aluminum Alloy Manufacturing:

It is an indispensable additive in aluminum alloy production. It can significantly improve the strength, hardness, wear resistance and corrosion resistance of aluminum alloys, improve the casting performance of aluminum alloys, make it easier to process and shape, and is widely used in automotive parts, aerospace structural parts, building doors and windows and other fields.

Steel industry:

Used as a deoxidizer in steel production, it can effectively remove oxygen from molten steel, reduce inclusions in steel, improve the purity and quality of steel, and improve the mechanical properties of steel, such as strength and toughness.

Silicone chemicals:

It is an important raw material for the production of organosilicon compounds. By reacting with substances such as methyl chloride, it can produce intermediates such as methylchlorosilane, which are further used to produce silicone products such as silicone rubber, silicone oil, silicone resin, etc. These products are widely used in building sealing, electronic packaging, cosmetics, medical and other fields.

Other fields:

It can also be used to produce polysilicon as a basic material for solar cells and semiconductor industries; in some special alloys and refractory materials, it can also play an important role in improving the performance of materials.
