One of the first things that can cause confusion when discussing ductile iron, or attempting to source it, is the varied number of ways it can be described. Because of its age and wide geographical spread many terms, sometimes local in nature, have grown up. All of the above terms can be used to describe the material. The terms nodular and spheroidal are used because the graphite forms spheres in the final structure.

  • Spheroidal Graphite Iron
  • Spheroidal Nodular Graphite Iron
  • Nodular Iron
  • Ductile Iron
  • SG Iron
