Description:

Industrial silicon 553 is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.

Specification:

Industrial silicon 553 is usually classified according to the content of three main impurities of iron, aluminum and calcium. In the silicon metal 553, the iron content is less than or equal to 0.5%, the aluminum content is less than or equal to 0.5%, and the calcium content is less than or equal to 0.3%.

1)Industrial silicon 553 ,as an alloying element for aluminium alloys for casting and extrusions.

2)Industrial silicon 553 ,as the basic raw material for silicons produced by the chemical industry.

3)Industrial silicon 553, as an alloy element in smelting ferro silicon in the steel industry, and as a reducing agent in many kinds of metal smelting.

4) Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
