ADI castings for high-strength, wear-resistant performance

ADI castings deliver extreme strength, fatigue resistance, and wear durability — without the weight or cost of steel. Our austempered ductile iron (ADI) components are engineered to perform in high-impact, high-stress environments across agriculture, mining, and industrial markets.

    Why choose ADI?

    Austempered ductile iron combines the toughness of steel with the efficiency of ductile iron casting. Through a specialized heat treatment process, ADI delivers high performance in parts exposed to shock, abrasion, or cyclical stress.

      Where ADI is used

      ADI castings are chosen for demanding applications that require strength, toughness, and reduced part weight. We cast ADI to spec for OEMs and manufacturers across heavy industries.

      Applications include:

      • Tillage tools and linkage components in agriculture
      • Mining housings, brackets, and impact-prone components
      • Suspension arms, hubs, and brake parts in automotive and off-road equipment
      • Chassis elements and underbody parts for heavy machinery
      • Industrial parts subject to repetitive load cycles
