ADI Foundry Manufacturing Process

What is Austempered Ductile Iron (ADI)?

Austempered Ductile Iron (ADI) is a group of ductile irons offering design engineers remarkable mechanical properties. It exhibits an excellent combination of high strength, ductility, toughness, fatigue strength, and exceptional wear resistance — unmatched by other cast iron grades.

ADI is nearly twice as strong as standard ductile iron while maintaining high elongation and impact resistance. It enables significant weight reduction and cost savings without compromising performance, making it an ideal substitute for forged or cast steel in demanding engineering applications.

Frequently Asked Questions

What is the main advantage of ADI over regular ductile iron?

ADI is nearly twice as strong as standard ductile iron while maintaining high ductility and toughness. It also offers superior wear and fatigue resistance.

Can ADI replace forged steel components?

Yes, ADI is a cost-effective and lightweight alternative to forged steel in many applications, including gears, suspension arms, and mining equipment.

What industries use ADI castings?

ADI is widely used in automotive, mining, agriculture, construction, and industrial machinery due to its durability and performance.

How does the austempering process work?

The process involves heating the ductile iron casting to an austenitizing temperature, then quenching it into a salt bath to form a unique ausferritic microstructure with superior mechanical properties.

Does ADI Foundry offer custom casting design?

Yes, our engineering team provides full support including 3D modeling, structural optimization, and material conversion consulting.
