Silicon Metal 553 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 processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemicalindustry. It is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance,highresistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.
