FeSi Alloy 68 Grade Granules Heavy Density For Casting Modification And Nodule Formation
FeSi Alloy 68% granules contain approximately 68% silicon with a heavy density (≈5.0-5.2 g/cm³) and are specially sized (typically 1-10 mm) for casting modification and nodular graphite formation in iron foundries.

Key Features
- Heavy density: Promotes rapid settling in treatment ladles for immediate reaction
- Granular form: Allows accurate metering and even dispersion during iron treatment
- Optimized Si level: Balances graphitization promotion with cost efficiency
Benefits in Casting
- Inoculation: Refines grain structure, reduces chill, and prevents hard spots in gray iron
- Spheroidization aid: Used with magnesium alloys to transform graphite flakes into nodules, producing ductile iron with high elongation and strength
- Process consistency: Granule sizing ensures repeatable treatment 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
