What are the different grades of silicon metals

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.

The classification of metallic silicon is usually classified according to the content of iron, aluminum and calcium,silicon metal is rich in silicon and is widely used in steel making, casting foundry, aluminium ingot production, purification and other industries.The content of different silicon metal grades varies and their applications are very different. The main common grades of silicon metal are 441, 553, 3303 and 2202, but in addition to these grades there are some lesser known grades, such as 421, 411 and 1101.

Metal silicon 441, 553 is mainly used for smelting in aluminum foundries.They can improve the already useful properties of aluminum such as castability, hardness and strength. Adding silicon metal to aluminium alloys makes them strong and light.Therefore, the sales of metal silicon 441 and 553 account for a relatively large proportion in the market.
