Preseed® preconditioner generates and stabilizes nuclei within the melt and is effective in grey, ductile, and compacted graphite irons. In addition, this preconditioner has been proven to be an effective furnace addition for cast irons. Small additions of Preseed® both increase the number of available nucleation sites in the base iron and, at the same time, stabilize these crucial particles to give a long-lasting effect that can be measured right through to the final properties of the solidified iron.

Preseed® enhances the formation of type “A” graphite formation in grey iron, using closely controlled additions of aluminum and zirconium to condition manganese sulfide particles that act as nuclei for graphite precipitation. Preseed® will also retain oxide activity in the base iron so that oxygen is available for the formation of magnesium silicate nuclei in ductile iron. This will generate more nuclei and increase nodule density.

  • Consistency in base irons leads to more uniform casting properties
  • Improved graphite morphology
  • Reduced shrinkage and carbide formation
  • Improved mechanical properties
  • Reduction in pig iron usage
