ADI - Austempered Ductile Iron | Zanardi Fonderie

Properties

ADI circle

ADI – Austempered Ductile Iron is a material that offers the combination of high fatigue resistance, wear resistance, toughness, lightness and extensive freedom in designing components together with good machining properties.
Through the iron casting process combined with the heat treatment, the mechanical properties achieved are the typical one of quenched&tempered steel. Austempered ductile iron (ADI) is an excellent opportunity to achieve ambitious goals to lighten and reduce the total production cost of the component.
Thanks to the integrated process and across the board skills that have been developed, ADI produced by Zanardi Fonderie has the best material quality and machinability currently available on the market.
