Alloy Series

FeSi 75# (Ferrosilicon 75) – High‑Grade Ferrosilicon for Steelmaking, Casting, and Special Alloy Production

FeSi 75# is a premium‑grade ferrosilicon alloy with silicon content stably controlled between 72% and 80% and low levels of impurities (Al, Ca, C, P, S). It serves as a high‑efficiency deoxidizer, alloying agent, and silicon source in steelmaking, foundry, and magnesium‑production processes, delivering reliable performance and consistent metallurgical results.

Produced from high‑purity quartz and carbonaceous reductants in submerged‑arc furnaces, our FeSi 75# features uniform composition, dense microstructure, low gas content, and excellent dissolution kinetics. It ensures high silicon yield, effective deoxidation, and precise silicon adjustment in electric‑arc furnaces, ladle treatment, and ductile‑iron inoculation, contributing to improved steel cleanliness, enhanced cast‑iron properties, and optimized process economics.

We supply FeSi 75# in standard lump sizes (10–100 mm), crushed/granular forms, and customized packaging, backed by full chemical certification and traceability. We provide technical support for alloy selection, addition methods, and process optimization, helping steel mills, foundries, and metallurgical plants achieve higher quality, lower costs, and more sustainable operations.
