Magnesium content in FeSiMg alloys produces the required graphite structure, which imparts tensile strength & elongation of S.G.Iron. These alloys are available in any combination of Magnesium, Calcium and Rare Earth, to suit individual Foundry process needs.

The addition of Rare Earth with the Magnesium is adequate to neutralize the harmful effects of the subversive elements in the base metal. Cerium content in the Rare Earth improves shape of nodule and increase number of nodules. Strict control of Mg, Ca and Ce in FeSiMg minimizes reactivity and gives more consistent result.
