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.

Key Features
- 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
Applications
- Production of ductile (nodular) iron for automotive components, pipe fittings, and machinery parts
- Inoculation of gray iron in sand casting and permanent mold operations
