553 silicon metal 10-50mm, 10-50mm refers to the size of silicon metal. The size of silicon metal usually includes natural lumps, lumps, granules and powder.

Natural lumps of silicon metal 553 are the form of silicon metal just produced, and the size is usually large. Basically, no customer directly purchases natural lumps;

Silicon metal 553 granules have a variety of sizes, such as 3-5mm, 5-10mm, 3-7mm, etc., which can be processed and screened according to the specific needs of customers;

Silicon metal powder 553 also has a variety of particle sizes, such as 200mesh, 325mesh, etc., which are processed according to the purchasing needs of customers, but the silicon content in silicon metal powder will be reduced, because there will be impurities during the processing process.

And 10-50mm and 10-60mm are the most purchased standard processing lumps of silicon metal. The effect can meet the requirements in use, and the silicon content can fully meet the purchasing needs of customers.

The main purpose

Cast iron alloying:

Increase Hardness: Adding metallic silicon to cast iron can significantly increase its hardness and strength.

Improve castability: Metallic silicon can improve the fluidity of cast iron, making the casting process smoother.

Steel alloying:

Increased strength: Through alloying, metallic silicon can enhance the strength and wear resistance of steel.

Improve corrosion resistance: The addition of metallic silicon can improve the corrosion resistance of steel.

Aluminum alloy production:

Toughening: Adding metallic silicon to aluminum alloy can improve its toughness and wear resistance.

Improve fluidity: Metallic silicon can improve the casting properties of aluminum alloys.

Photovoltaic and semiconductor industry:

Semiconductor materials: High-purity silicon is a key raw material for manufacturing semiconductor chips and solar panels.

In most smelting, casting, alloy production and other scenarios, the size of the feed port of the furnace (such as electric arc furnace, induction furnace) and the design of the feeding device (such as hopper, conveyor belt) are usually suitable for particles of 10-100mm. Particles in this size range will not cause dust and equipment clogging due to being too small, nor will they cause feeding difficulties and uneven accumulation in the furnace due to being too large (such as more than 100mm), which can ensure continuous and stable production.

As a subdivision range, 10-50mm has clear demand in scenarios such as small and medium-sized equipment and refined production. Although the procurement volume is less than the total amount of 10-100mm, the procurement is stable in the corresponding field and is an important subdivision specification.
