Silicon Metal 421 Grade

Silicon Metal 421 Overview Silicon Metal 421 is a metallurgical-grade silicon with a minimum silicon content of 99.2%. It is characterized by its low calcium content and well-controlled impurity levels, making it a reliable choice for applications requiring consistent quality. Available in both lump and powder forms with customized sizes, it features a silver-gray metallic appearance.   Applications Silicon Metal 421 is one of the most widely used grades for silicone production. Its balanced impurity levels and cost-effective performance make it a preferred choice for manufacturing silicone monomers.It is also suitable for manufacturing aluminum alloys and other metallurgical applications where controlled impurity levels are required.  If your application does not require lower calcium and aluminum content, Silicon Metal 441  and Silicon Metal 553 provides a versatile and cost-effective alternative. For higher-purity requirements, please explore Silicon Metal 2202 or Silicon M…
