Silicon metal is widely used in metallurgy, chemical industry, electronics and other industries. In the metallurgical industry, SIlicon Metal 553 Si #553 is mainly is an additive for non-ferrous alloys. In some non-ferrous metals, silicon metal can improve the strength, hardness and wear resistance of the base metal, and sometimes enhance the casting and welding properties of the base metal. Metallurgy grade silicon plays a important role in the aluminum alloy and aluminum profile industries.

In the chemical industry silicon metal is mainly a material to produce silicon-based compounds, such as silane, silicone, organic silicon, silicone oil, etc. Moreover, silicon is also useful in making semiconductor silicon, silicon ceramics, silicon carbide, silicon nitride, etc. At this time, chemical grade silicon metal is generally used, like Si 411, Si 421, Si 311.

Metal silicon 553 is the most common model among metal silicon products, and its silicon content is about 98%. Generally above 98.5%. The “553” in the number of metal silicon 553 represents that the contents of iron, aluminum, and calcium are below 0.5%, 0.5%, and 0.3% respectively.

Silicon metal 553 is an common additive for non-ferrous alloys and other metallurgical industries. It is a strong composite deoxidizer to replace pure aluminum to improve the utilization rate of deoxidizer, purify molten steel and improve the quality of steel. But its price is higher than ferro silicon.

The largest area of consumption of silicon metal 553 are the aluminum alloy and aluminum profile industries. The addition of silicon metal and Magnesium ingot to aluminum alloys can significantly improve various properties of aluminum alloys.In addition, silicon 553 is also a raw material for manufacturing high-purity semiconductor materials and silicone rubber.
