Ductile iron casting

Ductile Iron Casting

Ductile iron casting, also known as nodular or spheroidal graphite iron casting, is a manufacturing process that produces components using ductile iron, a type of cast iron with enhanced mechanical properties. Unlike grey iron, ductile iron features graphite in a spherical (nodular) form, achieved by adding magnesium or cerium to the molten iron before casting. This unique microstructure gives ductile iron its high strength, ductility, and impact resistance, making it a preferred material in demanding applications.

Key Characteristics:

  • High Strength and Durability: Ductile iron exhibits superior tensile and yield strength compared to grey iron, making it suitable for load-bearing and high-stress applications.
  • Improved Ductility: The spherical graphite structure allows the material to withstand elongation and deformation without cracking.
  • Good Machinability: Despite its strength, ductile iron remains machinable, facilitating precise manufacturing processes.
  • Wear Resistance: Its robustness ensures longevity in abrasive and corrosive environments.
