Ferrosilicon Zirconium Inoculant from China
Ferrosilicon Zirconium Inoculant is a ferrosilicon-based alloy with 2-5% zirconium additions, used for microstructure control in gray iron casting. It is classified under tariff item 7202.29.00 as 'other' ferro-silicon because the zirconium content makes it a complex ferro-silicon beyond standard binary compositions. This inoculant promotes graphite refinement and improves mechanical properties in cast iron.
