SILICON METAL

Silicon metal can be divided into metallurgical silicon and chemical silicon.
Metallurgical silicon is mainly used aluminum alloy and is a part of the aluminum alloy. Silicon aluminum alloy can meet the requirements of metallurgical strength and have the ability of rust protection in the field of automobile production. The content of phosphorus is very low, it's easier to make high quality aluminum alloy.
Chemical silicon is mainly used to produce silicone.
