Alloy Series

FeSi 72# (72% Ferrosilicon) – High-Purity Deoxidizer and Alloying Agent for Steelmaking and Casting

FeSi 72# is a standardized ferrosilicon grade with silicon content precisely controlled between 72% and 80%, making it an essential additive in steelmaking, foundry, and magnesium production. It delivers high silicon yield, strong deoxidation capability, and efficient alloying performance, ensuring improved steel cleanliness, enhanced mechanical properties, and optimized process efficiency in electric arc furnaces, ladle refining, and inoculation processes.

Produced through submerged‑arc furnace smelting using high‑grade raw materials, our FeSi 72# offers consistent chemical composition, low impurity levels (Al, Ca, C, P, S), and uniform lump/crushed particle size. It enables rapid dissolution, reliable silicon recovery, and stable metallurgical performance, making it suitable for a wide range of applications including carbon and low‑alloy steel production, ductile iron inoculation, and ferromagnesium smelting.

We provide steel mills, foundries, and metallurgical plants with standard and customized size fractions, traceable quality certification, and technical application support. Committed to reliability and performance, we serve as your trusted partner in achieving higher product quality, lower operational costs, and more sustainable metal production.
