FeSi Alloy Granules 70 Percent Silicon Bright Grey For Nodular Cast
Iron Inoculation Process
FeSi Alloy 70% granules contain around 70% silicon, with a bright grey metallic finish and granular form (typically 1–10 mm). They are engineered
for nodular cast iron inoculation, promoting uniform graphite nodule formation and reducing chill. | |

| Inoculation in ductile iron production |
- •Optimized Si level: Balances graphitization promotion with cost efficiency.
- •Granular form: Allows accurate metering and even dispersion in treatment ladles.
- •Bright grey appearance: Indicates fresh, low‑oxide material with high metallic content.
Benefits in Cast Iron Inoculation- •Refines grain structure: Prevents formation of hard spots and chill zones in gray iron.
- •Promotes nodular graphite: Works with magnesium treatment to produce ductile iron with high
elongation and strength.
- •Process consistency: Granule sizing ensures repeatable inoculation results
batch‑to‑batch.
- •Production of ductile (nodular) iron for automotive components,
pipe fittings, and machinery parts.
- •Inoculation of gray iron in sand casting and permanent mold
operations.
