FeSi Alloy Granules 70 Silicon Content Metallic Silver For Cast
Iron Spheroidization Process
FeSi 70 alloy granules contain about 70% silicon, with the balance iron and trace elements, and exhibit a bright
metallic silver color. Their granular form (typically 1–10 mm) is
optimized for controlled dosing during the spheroidization treatment of cast iron. | |

| Inoculant and spheroidizer in ductile iron |
- •Added alongside magnesium alloys to modify graphite morphology from
flake to spheroidal (ductile).
- •Promotes nucleation and controls chill depth.
- •Improves machinability, tensile strength, and elongation of
castings.
- •Granular shape enables even distribution in treatment ladles.
- •Reacts predictably to produce clean spheroidal graphite structures.
- •Minimizes fading, ensuring consistent treatment results
batch‑to‑batch.
- •Production of ductile (nodular) iron for automotive components,
pipes, machinery parts.
- •Inoculation of gray iron to refine grain and reduce chill.
