Ferro Silicon Lumps 72 Grade Metallic Grey Used As Inoculant In Foundry Production​

Ferro Silicon Lumps 72 Grade Metallic Grey Used As Inoculant In Foundry Production​


Ferro Silicon 72 grade lumps in metallic grey are widely employed as inoculants in foundry production to refine the microstructure of cast iron and improve its mechanical properties. With approximately 72% silicon content, these lumps promote the formation of fine graphite flakes or nodules during solidification, which enhances machinability, reduces chilling tendency, and minimizes shrinkage defects in castings. The metallic grey color indicates a relatively clean alloy with limited contamination, ensuring predictable inoculation effects. When added to molten iron just before pouring, the silicon in FeSi acts as nuclei for graphite precipitation, preventing the formation of coarse graphite that weakens the metal. This leads to castings with higher tensile strength, better wear resistance, and more uniform properties throughout the component. Commonly used in manufacturing engine blocks, cylinder heads, and machine bases, Ferro Silicon 72 lumps are easy to dose and integrate into automatic pouring systems. Their controlled composition and reliable performance make them indispensable in achieving consistent quality in ferrous castings across global foundries.
