Austempered Ductile Iron (ADI)

Austempered Ductile Iron (ADI)

ADI provides a high strength-to-weight material at a component price that is typically 20% less than that of steel.

Austempered Ductile Iron (ADI) is a specialty heat treated material that takes advantage of the near-net shape technology and low cost manufacturability of ductile iron castings to make a high strength, low cost, excellent abrasion-resistant material.  Six grades of ADI are available to address property combinations of high strength, abrasion resistance and toughness for converting from costly forgings, weldments and assemblies.

It may surprise you to know that in some applications ADI has replaced aluminum as a weight savings. ADI components are very competitive with steel forgings, castings, weldments, and aluminum forgings and castings.

Austempered Ductile Iron (ADI) has found successful applications across many industries, including Construction and Mining, Agriculture, Automotive, Heavy Truck, and Railroad.

Typical applications include:

  • Timing Gears
  • CV Joints
  • Steering Knuckles
  • Sprockets, Rollers, Idlers
  • Suspension Housings and brackets
  • Wear Plates
  • Wheel Hubs
  • Control Arms
  • Plow Points
  • Hitches
  • Crankshafts
  • Flanged shafts
