Silicon Iron Alloy FeSi75 Fine Sand 0-1mm Metallurgical Use

Ferro Silicon 75% Fine Grit (0.3–1mm) is engineered for applications demanding rapid dissolution and uniform silicon distribution-primarily foundry inoculation, cored wire filling, and welding electrode coatings. Unlike coarse lumps that dissolve slowly or ultrafine powders that create hazardous dust, this 0.3–1mm fraction delivers instant reaction kinetics with minimal airborne particles. Our FeSi75 fine grit maintains consistent Si (≥75%), strictly controlled Al/Ca/P/S, and narrow size distribution, making it the reliable choice for automatic inoculation lines, ductile iron production, and precision alloy blending where consistency directly impacts final casting quality.

Custom Chemistry Available:​ Al, Ca, C levels can be tuned to match your specific inoculation or alloy formulation requirements.

1.Instant Reaction Without Dust Hazard​ – 0.3–1mm hits the sweet spot: dissolves in seconds but won't create airborne silica like sub-0.1mm powders.

2.Consistent Inoculation Effect​ – Narrow size distribution ensures uniform silicon release, preventing chill zones and porosity in castings.

3.Clean Handling​ – Low fines mean less material loss in transfer and cleaner work environment (passes most factory dust inspections).

4.Batch-to-Batch Stability​ – Same chemistry every time, so your inoculation rate calculation stays valid across months of production.

5.Flexible Supply Format​ – Sold as-is or packed into cored wire, bags, or bulk-whatever fits your process.
