By introducing some trace metal elements such as Ca,Ba,Bi,Sb and Ti,etc.,the nodularizers can make the DI casting much better and reliable in as-cast conditions, which means thet there is no need for the DI castings carring out heat treatment, so avoiding oxidation or deformation when heated, and finally shortening kthe producton time and lowering the prodyction cost.

Soundness in microstructure with homogeneous composition, little segregation and lower MgO content.

The nodularization "take off" is delayed and the nodularization efficiency.

nodularization temperature is recommended at 1400-1500 and added at 1.4-1.8%.

Unique composition of special nodularizers for as-cast DI casting is welcomed and it can be made and supplied at convenience.

Supplied in the form of grains(3-25mm or 5-35mm)or following special requirement. Packed in plastic braids with inner wet-resistant plastic film. Per packed parcel is 25kg n.w.
