Automotive: aluminium is the green revolution material. In 5 years an increase by 20 kg per vehicle

Italian-Russian Aluminium Forum - Ferrario of Idra Group: “The car of the future? It’s made of aluminium”


Lightweight, recyclable and eco-sustainable. Aluminium is ideal for the automotive industry and figures show it. The quantity of aluminium used to make cars has in fact constantly increased over the last 30 years and will go on growing in the future: over the next 5 years the content of aluminium in cars will grow by 20 kg bringing the average per vehicle from 180 to 200 kg. This strategic value aspect has been dealt with during today’s Italian Russian Aluminium Forum – an online event organized by Metef (the expo dedicated to aluminium) and the Russian Aluminium Association – that will end tomorrow and has brought together entrepreneurs, associations and technical operators to discuss about the green material par excellence, aluminium, and its endless applications.



In the automotive sector, aluminium is and will be the material of the future” – declared Riccardo Ferrario of Idra Group, a Brescia-based leading producer of diecasting machines, increasingly used for large size, structural and complex light alloy castings. Over the year Idra has worked for the major carmakers such as Fiat, Chrysler and the Volkswagen group. “In Italy, the most recent estimates show that over 40% of the aluminium used (1.85 million tons in 2020) is destined to the automotive sector.”


“Its growth in the automotive industry – continues Ferrario – is due to its lightweight, structural resistance and durability. Moreover this light metal is a sustainability champion: aluminium reduces the carbon footprint and is ideal for full electric cars.”

Yet sustainability is not the only reason. Aluminium will be increasingly used in both petrol- and diesel-propelled internal-combustion engines as well as in the hybrid ones as the carmakers rush to produce more and more lightweight vehicles, which is crucial to meet the new and stricter limits of carbon dioxide emissions in the atmosphere.

And then comes savings. Among the different aluminium converting technologies available, diecasting will be the winner since it’s already used to produce large size castings that were simply impossible only a few years ago. Diecasting allows for massive investment reductions for the carmakers as well as streamlining of the chassis assembly lines generating cost and energy savings along the production cycle. Moreover the mechanical and physical properties of aluminium result in its 100% recyclability and consequently in the possibility to use it over and over for the production of new items.
