Ductile Iron

Soucy Belgen offers a wide range of ductile cast iron (spheroidal graphite). The latter is produced by adding magnesium just prior to casting, which crystallizes as graphite nodules before evaporating. This gives the ductile iron similar mechanical properties to those of steel.

Benefits of Soucy Belgen Ductile Iron

  • Cost that is relatively lower than steel and aluminum
  • Ductility (extensible)
  • Resistance to crack formation
  • Strength
  • Resistance to impact
  • Versatility

Applications:

Shaft and drive components, valve, coupling, and pipe
