Ductile or Nodular Iron is obtained through the controlled introduction of magnesium, low proportions of sulfur and phosphorus in cast iron. In this way an extraordinary modification in the metal microstructure is obtained, depositing carbon in the ferritic matrix in the form of spheres.
The result of this change in structure is a stronger, stronger and more elastic iron.
Nodular or ductile iron offers the meltability, machinability, and corrosion resistance of gray iron while adding the high strength, ductility, and hardenability of steel. Our ductile iron castings are well known throughout the industry for their high impact resistance and high modulus of elasticity and strength, resulting in increased load capacity with less deflection.
We cast and machine pieces in nodular or ductile iron in all its classes from .5 lb to 440 lb reaching an installed production capacity of 720 tons per year in three shifts.
