Silicon Metal 553 Standard And Off Grade

What is Silicon Metal 553 Grade?

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 specification:

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.

Silicon metal classification：

The classification of metallic silicon is usually classified according to the content of iron, aluminum and calcium, silicon metal can be divided into different grades such as silicon metal 553/441/3303/2202 and 1101.
