silicon metal for aluminum ingot

The Description of the Silicon Metal

Silicon Metal processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemical industry. It 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.


The Application of the Silicon Metal

1. Used in aluminum: An additive to aluminum alloys, silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly. 

2. Used in organic chemicals: Silicon metal is used in manufacturing a number of sorts of silicones, resins, and lubricants. 

3. Used in electronic parts: Silicon metal is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc.
