Silicon Metal Description
Metallic silicon (Si) is an industrially refined elemental silicon that is mainly used for the production of organic silicon, the production of high-purity semiconductor materials, and the preparation of special-purpose alloys. Silicon-aluminum alloy is the most commonly used silicon alloy. Silicon-aluminum alloy is a reliable composite deoxidizer that improves the utilization rate of the deoxidizer when replacing pure aluminum in the steelmaking process. It also cleans molten steel and improves its quality. Silicon-aluminum alloy has low density, low coefficient of thermal expansion, excellent casting performance, and wear resistance.
