Product Overview - Ferrosilicon 15% & 45%
Our Ferrosilicon 15% and 45% are engineered alloy products designed for reliable performance in steelmaking, foundries and metallurgical operations. Manufactured across our facilities in Eurasia, Turkey and Armenia, these grades deliver stable chemistry, consistent sizing and strong deoxidation efficiency across a wide range of alloying and melting applications.
FeSi 15% is optimized for carbon-rich foundry environments, where controlled silicon addition and cost-effective deoxidation are required. FeSi 45%, with its higher silicon content, provides strong reductive power, improved fluidity and enhanced alloy stability during steel and cast iron production.
Both products are processed under strict quality control to keep impurity levels low, granulation uniform and melting behaviour predictable — with a Certificate of Analysis included on every order.
Milled Ferrosilicon 15%
A reliable, stable suspension ideal for medium-density DMS circuits. Controlled milling and angular particle shape deliver consistent performance at the lowest operating cost.
Milled Ferrosilicon 45%
Engineered for high-accuracy sink-float operations where density control matters most. Fine, angular particles guarantee cleaner separation and superior stability.
Premium Milled Ferrosilicon
Exceptional purity, long service life and the highest stability in demanding DMS plants — for clients who want the best possible performance.
Engineered Custom Grade
Need a particle band or silicon window outside our standard ranges? We size and blend to your furnace or DMS circuit's spec on request, including fine powder for welding electrode production.
