Silicon Metal 553

Silicon metal is a gray and shiny semiconductor metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. The silicon metal is produced from quartz and coke in an electric furnace, and the content of silicon element is about 98% (in recent years, with the content of 99.99% Si is also named silicon metal), the other impurities are mainly iron, aluminum, calcium and so on. The classification of metallic silicon is according to the content of iron, aluminum and calcium, silicon metal can be divided into different grades such as 553, 441, 411, 3303, 2202, and 1101.

What is silicon metal grade 553?
Silicon metal 553 is a commonly used grade. In the metal silicon 553, the silicon content should be as high as 98.5%. The contents of iron, aluminum, and calcium are 0.5%, 0.5%, and 0.3% respectively. Silicon 553 and silicon 441 are mainly used in the production of aluminum ingots. Adding silicon metal to aluminium alloys makes them strong and light.

Silicon metal 553 specifications:

Silicon metal 553 generally the diameter is 10-50mm,50-100mm,10-100mm or other sizes as customer’s request. Silicon metal is a gray and shiny semiconductor metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys which smelted from quartz and coke in an electric furnace.

Uses of Silicon metal 533 :

Silicon metal 553 is widely used in refractories, powder metallurgy industry, it is an excellent antioxidant. Adding silicon metal 553 in the refractory material can first react with oxygen to form a new mineral phase, close the pores, improve the density, prevent the penetration of slag iron, so as to improve the product’s high temperature resistance, wear resistance and oxidation resistance of the product.

Purpose of silicon metal:

1. Use for Al alloy product: could be added in aluminum alloys, to enhance the strength of the alloy, increase its anti-oxidation and corrosion resistance, decrease its density and coefficient of thermal expansion, meliorate its casting performance, and make the alloy have a high impact resistance and pressure resistance.

2. Used for cold-rolled silicon steel product: After add silicon metal in steel, it could greatly improve the magnetic properties of steel, increase its permeability, reducing the hysteresis and eddy current losses.

3. Use for high purity semiconductor product: Due to the high melting point of silicon, good thermal stability, large band gap, rich in resources, with technology has been improving, integrated circuits and large-scale integrated circuits which made from silicon semiconductor have been used in various fields, the demand is growing up year by year.

4. Use for organic silicon product: silicone, silicon resin, silicone oil Silicone: Maintain flexibility in the range of-700℃ to 2000℃, could be used for high temperature gaskets and cold insulation materials. Silicon resin: For the production of insulating paint, heat temperature of 180 ~ 2000℃, can also be used for the production of high temperature coatings. Silicone oil: For the production of senior lubricant, polishing agent, fluid spring, and the dielectric liquid, also could be processed into a colorless transparent liquid, sprayed on the building for waterproofing. Silicon metal is more and more widely used in organic silicon industry, the usage amount is tend to exceed aluminum alloy industry.

5. Use for heat-resisting material product: For the production of Si3N4, heat-resistant, wear-resistant, and corrosion-resistant. Making the coated material can prevent oxidation. Siliconized steel surface can improve the corrosion resistance of the steel.
