Silicon for aluminum alloy

Appearance:The surface and section of Industrial silicon should be clean. It is not allowed to have slag inclusions, powdered silicon bonding and other foreign materials in the non-smelting process.

Particle size:Industrial silicon is supplied in blocks or pellets. The particle size is less than 10mm and the size is less than 5%. If other particle sizes are required, Customized production is available according to customer needs.
