The nodularizer is a casting material for nodular cast iron castings with the high chemical homogeneity, small element deviation, MgO content <1.% smooth spherification with high sbsorptivity, good adaptability, and good anti-fading capacity.

The product is characterized by a dense texture, homogenous integrity and high flexibility. The unit core material weight is stable and the absorption rate is steady. Improvement of the spherification level can be achieved.
