Ferro Silicon 70 Silvery Gray Alloy Briquettes for Casting and Smelting Industries Worldwide​

Ferro Silicon 70 silvery gray alloy briquettes are a globally trusted solution for casting and smelting industries, blending high silicon content (≈70%) with a compact, easy-to-handle form. The silvery-gray appearance reflects high purity, indicating minimal contaminants that could impair metal quality. In casting, briquettes act as deoxidizers and inoculants: added to molten iron or steel, they refine grain structure, reducing shrinkage cavities and improving fluidity for intricate molds (e.g., engine blocks, pump housings). Their briquette form—compressed into dense, uniform shapes—prevents dusting during handling, enhancing workplace safety, and ensures controlled dissolution, avoiding sudden temperature drops in furnaces. For smelting, they aid in slag formation, capturing impurities like phosphorus and sulfur, thus purifying the final metal. Compatible with cupola, induction, and arc furnaces, they suit small foundries to large smelters worldwide. The briquettes’ stability during storage (resisting moisture absorption) ensures consistent performance batch after batch. By merging efficiency, safety, and global applicability, Ferro Silicon 70 briquettes empower casters and smelters to elevate product quality and streamline operations across continents.
