Casting Ferro Silicon Particles are key additives for the foundry industry, mainly composed of silicon (Si: 65%-95%) and iron (Fe), with trace alloying elements like aluminum (Al), calcium (Ca) to optimize performance. Featuring uniform composition, stable inoculation effect, and low slag generation, they are widely used in ductile iron, gray cast iron production, and casting alloy manufacturing. Our products adopt precision processing technology to ensure consistent quality, effectively improving casting quality and production efficiency.
