• Aluminum Alloy Production

  Silicon Metal 2202 is widely used as a key alloying additive in aluminum alloy production. With proper addition, it significantly improves the strength, hardness, wear resistance and corrosion resistance of aluminum materials. It is widely adopted in manufacturing automotive parts, aerospace components, construction profiles and various high-strength casting alloys.

• Silicone Chemical Industry

  Silicon Metal 2202 acts as an essential raw material for manufacturing organosilicon products, including silicone rubber, silicone oil and silicone resin. Its low impurity content helps reduce unwanted byproducts during reactions, improves production stability and delivers stronger quality assurance for final silicone products.

• Metallurgy & Refractory Materials

  In the metallurgical industry, Silicon Metal 2202 is applied in silicon steel production, steel deoxidation and refractory material formulations. It helps optimize the performance of silicon steel and enhances the high-temperature stability and service life of refractory products, making it widely used in steel and high-temperature industrial sectors.

• Semiconductor & Photovoltaic Fields

  With strict control over calcium, iron, aluminum and other trace impurities, Silicon Metal 2202 can be used as a raw material for producing polysilicon and certain high-purity silicon materials, providing stable material support for the photovoltaic and electronics industries.

Compared with common grades such as 553, 441 and 3303, Silicon Metal 2202 imposes stricter limits on Fe, Al and Ca impurities, making it more suitable for applications demanding high raw material purity and composition stability.

A lower iron content helps improve performance consistency in precision aluminum alloys, while lower aluminum and calcium contents support better quality control in organosilicon synthesis and polysilicon raw material processing.

In contrast, grades 553, 441 and 3303 are mostly used in general metallurgical deoxidation, standard casting and other less impurity-sensitive scenarios. Silicon Metal 2202, however, is better suited for mid-to-high-end applications including precision aluminum processing, silicone chemical manufacturing and photovoltaic raw material production, achieving a strong overall balance between quality stability and procurement cost.

We can provide free samples, product data, test reports and relevant supporting information based on your requirements, helping you quickly evaluate the product and move forward with material selection and procurement.Should you need further details regarding production and supply capacity, please feel free to contact us for discussion.

Q:Is silicon a metal or nonmetal?

A:Silicon is classified as a metalloid (or semi-metal), with properties between metals and nonmetals. That is why the commercial grade we offer is commonly called silicon metal, referring to its metallic appearance and conductivity, even though it is not a true metal element.

Q:What is silicon metal used for?

A:Silicon metal (including grade 2202) is widely used in three main fields:

• Aluminum alloy production (to improve strength and corrosion resistance)
• Silicone/chemical manufacturing (raw material for silicone rubber, oil, and resins)
• Metallurgy and photovoltaic applications (deoxidizer and polysilicon feedstock)

Q: What affects the price of silicon metal?

A:The price of silicon metal depends on several key factors:

Grade and purity (higher grades like 2202 cost more than 553/441)

Raw material and electricity costs

Order volume and lead time

Market supply and demand conditions

Q: What is the HS code for silicon metal?

A:The standard HS code for silicon metal is 2804.69. It is used for customs declaration and international shipping, and we can provide complete documentation for export clearance.

Q: What is the difference between silicon metal grades 2202 and 553?

A:Compared with 553 grade, silicon metal 2202 has stricter control over Fe, Al, and Ca impurities. This makes it suitable for higher-end applications such as precision aluminum alloys and silicone production, while 553 is typically used in general metallurgy and low-to-moderate casting processes.
