Silicon metal 553 applications

Silicon grade 553 can be used as silicon aluminum alloy.

Silicon aluminum alloy is a strong composite deoxidizer. Replacing pure aluminum in the steelmaking process can improve the utilization of deoxidizers. Silicon aluminum alloy has low density. Low thermal expansion coefficient. Good casting properties and abrasion resistance. The castings it casts have high impact resistance and good high-pressure compactness. It can increase service life. Silicon aluminum alloys are used in the production of spacecraft and automotive parts.

Silicon Metal is a very important industrial product can be used in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device and many other industries. It's known as the "salt" of modern industries. Metal silicon is made from quartz and coke in electric heating furnace smelting products. The main ingredient of silicon content is about 98%. The rest of impurities is iron, aluminum and calcium etc.

Silicon Metal lump was produced in electric heating furnace by quartz and coke. Quartz will be redox and became molten silicon liquid. After cooling, it will be solid as we see. The primal silicon metal lump is very large. Then it will be made into smaller lumps which we call standard size. Silicon Metal Lumps will be 10-100mm.

Typical models includes: Silicon Metal 2202; Silicon Metal 3303; Silicon Metal 441; Silicon Metal 553, Silicon Metal Off Grade.
