The aim of this paper is to contribute to the creation of a sustainable economy in the EU aluminum manufacturing industry for cars and electric vehicles. The sector needs sustainable, high-performance sources of aluminium, which is only possible by generating a new aluminum ecosystem. The automotive industry is facing multiple challenges to achieve the objectives of the European Green Deal. It must produce new high-performance but lightweight materials and decrease dependence on imported raw materials, while creating a sustainable economy for the future. One of the fundamental aspects of aluminum concerns its recycling capacity, which occurs 100% and does not cause the loss of the original properties, making it advantageous from an economic and ecological point of view. Aluminum is very versatile and is ideal for producing light but durable components such as car structures, where using aluminum alloys improves mechanical performance; furthermore, it is an indispensable material for modern industry, as it contributes to the development of advanced technologies and sustainable solutions. Furthermore, new heat treatments and manufacturing processes have been introduced (just think of the T5 treatment) which further improve the properties of aluminum alloys, making them highly suitable for complex structural applications; it is thought that continuous research and innovation in the field of aluminum alloys will lead to opening new frontiers in the field of materials engineering, consolidating the role of aluminum as a pillar of industrial technology.
L'obiettivo di questo elaborato è contribuire alla creazione di un’economia sostenibile nell’ industria manifatturiera dell’alluminio per le automobili e i veicoli elettrici dell’UE. Il settore ha bisogno di fonti di alluminio sostenibili e ad alte prestazioni, il che è possibile solo generando un nuovo ecosistema dell’alluminio. L’industria automobilistica sta affrontando molteplici sfide per raggiungere gli obiettivi del Green Deal Europeo. Deve produrre nuovi materiali ad alte prestazioni ma leggeri e diminuire la dipendenza dalle materie prime importate, creando al contempo un’economia sostenibile per il futuro. Uno degli aspetti fondamentali dell’alluminio riguarda la sua capacità di riciclaggio, che avviene al 100% e non causa la perdita delle proprietà originali, rendendolo vantaggioso sotto il punto di vista economico ed e cologico. L'alluminio risulta molto versatile ed è ideale per produrre componenti leggeri ma durevoli come le strutture delle automobili, dove impiegare le lege di alluminio migliora le prestazioni meccaniche; inoltre, risulta un materiale indispensabile per l’industria moderna, in quanto contribuisce allo sviluppo delle tecnologie avanzate e delle soluzioni sostenibili. Sono stati, inoltre, introdotti nuovi trattamenti termici e processi di lavorazione (basti pensare al trattamento T5) che migliorano in modo ulteriore le proprietà delle leghe di alluminio, rendendole al massimo adatte alle applicazioni strutturali complesse; si pensa che la continua ricerca e innovazione nel campo delle leghe di alluminio porti ad aprire nuove frontiere nel campo dell’ingegneria dei materiali, consolidando il ruolo dell'alluminio come pilastro della tecnologia industriale.

Abstract
The aim of this paper is to contribute to the creation of a sustainable economy in the EU aluminum manufacturing industry for cars and electric vehicles. The sector needs sustainable, high-performance sources of aluminium, which is only possible by generating a new aluminum ecosystem. The automotive industry is facing multiple challenges to achieve the objectives of the European Green Deal. It must produce new high-performance but lightweight materials and decrease dependence on imported raw materials, while creating a sustainable economy for the future. One of the fundamental aspects of aluminum concerns its recycling capacity, which occurs 100% and does not cause the loss of the original properties, making it advantageous from an economic and ecological point of view. Aluminum is very versatile and is ideal for producing light but durable components such as car structures, where using aluminum alloys improves mechanical performance; furthermore, it is an indispensable material for modern industry, as it contributes to the development of advanced technologies and sustainable solutions. Furthermore, new heat treatments and manufacturing processes have been introduced (just think of the T5 treatment) which further improve the properties of aluminum alloys, making them highly suitable for complex structural applications; it is thought that continuous research and innovation in the field of aluminum alloys will lead to opening new frontiers in the field of materials engineering, consolidating the role of aluminum as a pillar of industrial technology.File | Dimensione | Formato | |
