ADI Market Overview

Over twenty years, heat treatment specialists and equipment engineers have refined the Austempering process and plant to enable reliable production of high grade Austempered materials. This has fuelled demand and a family of Austempered Irons and Steels are now routinely produced. Of these Austempered Ductile Iron is increasingly the material of choice as designers and engineers seek cost effective performance from their components and systems. In particular, manufacturers engaged in moving parts and safety critical items have benefited from increased strength, greater wear resistance, noise reduction and weight saving.

ADI is now established in many major markets:

  • Agricultural Equipment
  • Construction Equipment
  • Gears/Powertrain
  • Heavy Truck/Trailers
  • Light Vehicles and Buses
  • Mining/Forestry Equipment
  • Railway
  • Farm and Oilfield Machinery
  • Conveyor Equipment and Tooling
  • Defence
  • Energy Generation
  • Sporting Goods

ADI is also finding new markets. In particular the burgeoning Renewable Energy field has identified ADI components to replace conventional materials solutions. Meanwhile specialist applications of the other Austempered cast irons (AGI, and CADI) are growing and there are niche markets for the unique Carbo-Austempering process.
