Micronized Ferro Silicon Powder (Si 15%)
Micronized Ferro Silicon (Si 15%) is a finely milled alloy powder made from high-grade ferrosilicon, produced for applications that need high reactivity and tight particle control. With 14–16% silicon, it gives steelmakers, foundries and alloy producers a dependable way to manage deoxidation, density and thermal behaviour without guesswork.

Product Overview — Micronized Ferro Silicon (Si 15%)
Micronized Ferro Silicon (Si 15%) is milled from high-quality ferrosilicon and processed down to a fine, uniform particle size that reacts quickly and predictably in the melt. At 15% silicon, it sits in a useful middle ground: enough reducing power for real metallurgical work, without paying for a full-strength grade you don't actually need.
Because the powder is engineered rather than simply crushed, foundries and steel producers get more consistent alloying, cleaner deoxidation and fewer surprises from one batch to the next. Ferrosilicon.co supplies this grade with full export documentation, so orders move from quotation to port without unnecessary delays.
Fe-Si 15
Standard micronized grade, 14–16% Si, balanced for general deoxidation and alloying work.
Fe-Si 53
Same silicon range with added titanium (3–5% Ti) for applications where extra stability is required.
Fe-Si 103
TiO₂-enhanced variant (3–8%) for specialized welding and metallurgical powder formulations.
Custom Grade

Best Quality Micronized Alloy
We produce this Ferro Silicon (Si 15%) from carefully sourced raw material and run it through the same micronizing line every time, so particle size doesn't drift from one lot to the next. Each batch is checked against ISO and ASTM reference methods before it leaves the plant, which keeps silicon content, impurity levels and metallurgical performance where our customers expect them to be.

Reliable Global Supply
Ferrosilicon.co ships from production and stocking points in Eurasia, Armenia and Turkey, which gives us more flexibility on lead time than working out of a single country. We handle FOB, CIF and DDP terms depending on what the buyer needs, and we keep quotes and paperwork moving so a trial order doesn't turn into a two-week wait.

Proven Industrial Performance
In practice, this grade performs well in steelmaking, foundry work and dense media separation, where the finer particle size supports faster, more even reactivity. Customers running tighter deoxidation targets, or needing better density control, tend to notice the difference fairly quickly once they switch a line over.
