Ferro alloys are composite of iron and other elements such as silicon manganese and chromium when incorporated with alloy steel ferro alloys are used to alter the material properties of the steel.

Product Description: Industrial silicon powder is called silicon metal powder. It is silver gray or dark gray powder with metallic luster. 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. Application: 1. Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance. also as to be iron base alloy additive, the alloy pharmaceutical of silicon steel, thus improve the steel hardenability 2. To the chemical line of organic silicon, industrial silicon powder is basic raw material that high polymer of organic silicon formatting. Such as using for producing organic monomer, silicon oil, silicon rubber antiseptic to improve the characteristics of insulating, corrosion-resistance and waterproof performance etc. 3. To the electronic industry, it is the base material used in the manufacture of high purity polycrystalline and monocrystalline silicon. These products are used in the manufacture of semiconductors, microchips for computers and solar cells used to capture electrical energy from the sun.
