FeSi Alloy Granules 70 Silicon Content Metallic Silver For Cast Iron Spheroidization Process
| Property | Typical Specification |
|---|---|
| Si content | ~68-72% (nominal 70%) |
| Form | Granules/spheroids |
| Color | Metallic silver |
| Impurities | Low Mg, Ca, rare earths if specified |
| Main use | 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
