Silicon metal powder(Si powder) is a special material which can be used in metallurgy. It mainly consists of silicon element and is used to improve the castability. It can be used to improve the surface quality of metals and reduce the oxidation of metals. Silicon powder is often used as steel and aluminum alloy materials in metallurgy, silicon powder can also be used for non-ferrous metal casting, such as brass, pure zinc and alloys, semiconductor materials and so on.
We produce metal silicon powder after screening, washing, drying and other processing to achieve the granularity and purity requirements of customers.
In addition, the refined metal silicon powder is packed into airtight packaging to prevent its moisture, oxidation, etc.
