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.
