Iron Silicon alloy granules containing 70% silicon are specifically formulated for cast iron inoculation and nodularizing treatments, enhancing the metal's graphitic structure and mechanical characteristics. The granulated form ensures easy and accurate dosing into molten iron, promoting uniform distribution during treatment.

As an inoculant, the silicon encourages the formation of fine, evenly distributed graphite flakes, which improve machinability, reduce chill zones, and minimize casting defects like shrinkage cavities. In nodularizing applications, it works synergistically with magnesium or rare earth additives to transform flake graphite into spheroidal nodules, dramatically increasing ductility and tensile strength.

This makes the alloy ideal for manufacturing ductile iron pipes, automotive components, and heavy machinery parts that require both strength and flexibility. The 70% Si content strikes a balance between effectiveness and cost, while the granules resist dusting and facilitate safe handling. Foundries worldwide depend on this alloy to consistently produce high-integrity cast iron with superior performance characteristics.
