Product Description

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.

Product Specifications

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

Role in Cast Iron Processing

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

Process Advantages

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

Applications

Production of ductile (nodular) iron for automotive components, pipes, machinery parts
Inoculation of gray iron to refine grain and reduce chill
