Zanardi Fonderie S.p.A.
An Italian spheroidal graphite iron foundry specialised in spheroidal graphite iron and austempered ductile iron
Zanardi Fonderie: development and production of castings in spheroidal graphite iron (GJS), austempered ductile iron (ADI) and isothermal ductile iron (IDI).
Specialists in austempering heat treatment.
At Zanardi Fonderie S.p.a. we are specialised in cast parts in spheroidal graphite iron (GJS), austempered ductile iron (ADI) and isothermal ductile iron (IDI). One of our key strengths is precisely our expertise acquired in austempering heat treatment.
Thanks to the integrated process in our production plant in Minerbe in the province of Verona, we offer clients a single point of contact, partnering them through all stages from the design of the component to the delivery of the finished product. Design, melting, heat treatment, deburring, mechanical machining, coating, quality control and certification perfectly coexist in our plant to guarantee clients the supply of cast parts in spheroidal graphite iron (GJS), austempered ductile iron (ADI) and isothermal ductile iron (IDI), ready for assembly.
Zanardi Fonderie manufactures all grades of spheroidal graphite iron (GJS), austempered ductile iron (ADI), alongside the production of isothermal ductile iron (IDI), a material patented by Zanardi Fonderie, all in compliance with international standards.
Spheroidal graphite iron
A widespread material characterised by the spherical form of the graphite, with mechanical strength and toughness such as to allow its use in countless applications in the broadest range of fields. The new grades of solid-solution strengthened ferritic ductile irons, also known as high silicon ductile iron (updated version of EN 1563), have opened up to an even greater number of applications.
Austempered ductile iron
An excellent and efficient alternative to steel casting and forging. An excellent opportunity to reduce the weight of the materials compared to traditional ones. Austempered ductile iron (ADI) is a material that offers fatigue strength, wear resistance, toughness, lightness, ample freedom of design of parts and good machinability.
Isothermal ductile iron
An interesting intermediate material between ADI and GJS, which doesn’t require alloying elements for greater thickness values. The possibility to obtain IDI without alloying elements enhances the performance of this material both in terms of quality and cost savings for very thick parts requiring static and fatigue strength. The IDI grade is patented by Zanardi Fonderie S.p.a.
We offer the market a one-stop shop for the supply of treated, machined, tested and certified cast iron castings.
We are a foundry specialised in small and medium production series from 1 kg to 120 kg of raw and machined parts, in spheroidal graphite iron (GJS), austempered ductile iron (ADI) and isothermal ductile iron (IDI), a material patented by Zanardi Fonderie. Experience, reliability and the continuous search for innovative solutions are the key elements that have forever distinguished Zanardi Fonderie and the quality of its products.
Supply chain management
Our aim to be a single point of contact for our clients, guaranteeing an integrated and complete process, has inspired us to create a capillary network of external subcontractors able to expand and complete the range of products and services offered to clients. To ensure the most efficient management, in recent years the company has invested in the development of a structure that coordinates and presides over the entire supply chain.
Backed by more than 30 years’ experience in the field of austempering, Zanardi Fonderie is a benchmark company in the field of spheroidal graphite irons, both with austempered ductile iron (ADI) and isothermal ductile iron (IDI) patented by Zanardi Fonderie. Through the new Zanardi Austempering brand, we offer third-party treatments on behalf of all European spheroidal graphite iron foundries.
Design, development and manufacture of axle pins, track pins, planetary reducers. In this section we tell you about real cases in which Zanardi Fonderie has collaborated with clients to create specific components, successfully identifying solutions to industrial problems and improving the final product.
Environment and safety
Respect for the environment and visitor and employee safety are at the heart of our company policy. For years we have made regular investments to guarantee a safe and healthy workplace and sustainable manufacturing, with respect for the environment and the people who work in our plants, because we believe in virtuous and sustainable development for future generations.
90 years of history
A foundry with a remarkable 90-year history. Founded in 1931, today the company is run by the fourth-generation Zanardi family. With more than 200 employees, the foundry has always stood out for its technological innovation, research and quality processing of austempered ductile iron (ADI) and cast iron in general.
