Ferrosilicon Magnesium Alloy 75Mg from Canada
Ferrosilicon magnesium alloy containing 75% silicon, over 2% magnesium by weight, used primarily as a nodulizing agent in ductile iron production. This ferroalloy falls under HTS 7202.29.0010 due to its ferrosilicon base with elevated magnesium content for magnesium treatment in foundries. It improves the mechanical properties of cast iron by forming nodular graphite.
