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.

aluminum ingot factory/aluminum material manufacturer
1. Aluminum alloy
It can improve the existing properties of aluminum such as castability, hardness and strength. Adding silicon metal to aluminum alloys makes them strong and lightweight.
Therefore, they are increasingly used in the automotive industry. For replacement of heavier cast iron parts. Auto parts such as engine blocks and tire rims are the most common cast aluminum silicon parts.
2. Solar industry and electronics industry
Silicon metal can also be used as a basic material in the solar and electronics industries. For example, it can be used to make solar panels, semiconductors and silicon chips.
3. Production of silicone rubber, silicone resin, silicone oil, etc.
