ADI, AGI and CADI - Some Advantages
All heat treatments create dimensional change but with ADI this effect can be minimsed. The process is isothermal which means that components of the same incoming chemistry will grow the same way every time.
Batch-to-batch and part-to-part, your components will have predictable growth from the Austempering process. That means you can design the dimensional change into your component and let it grow to its tolerance.
The final properties (grades) of the ADI are governed by the austempering temperature and duration.
Based on customer input, our proprietary computer models can make accurate material and process selections and predict these properties. We can then assist the design engineer to find the optimum and most efficient solutions.
The Austempering of Grey Iron forms AGI, a material with excellent damping and wear resistance. Current applications include cylinder liners and bearing collars.
Carbidic ADI (CADI) is a new material formed with a matrix of ausferrite and carbides to add strength and wear resistance to ductile iron parts. The result is a premium, engineered iron with longer life and greater wear resistance than ADI 1400 (EN1564).
Applications for CADI are to be found in off-highway vehicles, agricultural equipment, railroad car, truck, construction, mining, general industrial, material handling, and ground engaging components.
