Ductile cast iron, also known as ductile iron or nodular cast iron, is a high-performance cast iron alloy in which carbon is present in the form of spheroidal (nodular) graphite. This unique graphite structure significantly improves ductility, toughness, and impact resistance compared to gray cast iron.
Ductile cast iron combines the casting advantages of cast iron with mechanical properties close to steel, making it a preferred material for load-bearing and pressure-sensitive applications.
For purchase inquiries, please contact our commercial and sales department.
The ductile cast iron composition is similar to gray cast iron but with lower sulfur and phosphorus levels and the addition of magnesium to form spherical graphite.
Typical Chemical Composition:
This optimized ductile cast iron chemical composition ensures superior mechanical performance and structural integrity.

Ductile cast iron is widely used due to its balanced mechanical and physical characteristics.
Key Properties of Ductile Cast Iron:
Ductile cast iron density: approximately 7.1–7.2 g/cm³, depending on alloy grade.
The defining feature of ductile iron is its spheroidal graphite structure, dispersed within a ferritic, pearlitic, or mixed matrix.
This structure:
