Zanardi Fonderie launches a new brand dedicated to the heat treatment subcontracting
Austempered Ductile Iron (ADI) is an important driving force in the development of the cast iron foundry market. For 30 years, Zanardi Fonderie S.p.A., an Italian company founded in Minerbe (Verona) in 1931, has believed and invested in the potential of this innovative material which offers machine manufacturers a valid alternative to steel components, maximising the performance/costs ratio in numerous applications.
In 2019, Zanardi Fonderie established the new “Zanardi Austempering” brand to offer all foundries a third-party heat treatment service and act as a single reference point for the conception, design, development and certification of the material.
“We make our furnaces available to foundries who, like us, view austempered iron as an excellent opportunity to grow, develop and innovate”, says Fabio Zanardi, president and CEO of Zanardi Fonderie S.p.A. “Our professional staff are trained to assist customers in all process stages, from the chemical analysis to the complete certification of the austempered material”.
By making use of three AFC-Holcroft UBQA 36-72-36 furnaces which allow excellent results to be achieved in terms of process repeatability, Zanardi can treat castings of up to 840x1705x890 mm in size, weighing up to 1000 kg and different batches, from small series to large-scale automotive production.
“Zanardi Austempering” offers the market all ADI grades in compliance with the international standards (ISO17804, EN1564 and ASTMA897/A897M), as well as other material grades, such as Austempered Grey Iron (AGI) and austempered steel. It also makes the company’s latest patented technology available to foundries: the IDI grade (Isothermed Ductile Iron). This Italian company is always at the forefront of austempering development and actively partners with the major academic institutes, as well as participating in international committees governing material regulations.
