Mold Inoculants


GERMALLOY and SMW Insert are solid cast inserts used for the mold inoculation of ductile iron. They are either placed in the drag portion of the mold or anchored in the pouring basin of very large castings. GERMALLOY is widely used to improve the nodule count of graphite within a casting, as well as enhance its mechanical properties. SMW Insert inoculants, on the other hand, are well known for their ability to eliminate the formation of chunky graphite in heavy section ductile iron. OPTIGRAN is the mold inoculant for gray iron. It provides finer Type “A” graphite in gray iron.
