Ductile Iron / Nodular Cast Iron
Ductile iron is an iron-carbon alloy characterized by the presence of graphite in a spheroidal (nodular) form. This spheroidal graphite significantly enhances the material’s ductility, toughness, and impact resistance while maintaining excellent castability and wear resistance. Ductile iron is widely used in the production of high-strength castings, such as automotive components, construction machinery, robot bodies, and key structural parts for RV reducers.
Why choose this material:
- High strength, toughness, and fatigue resistance;
- Good machinability and heat-treatment characteristics;
- Excellent castability, making it suitable for producing complex structural parts and thin-walled components;
- Relatively low manufacturing costs;
- Widely used in the robotics and construction machinery sectors.
