Automakers are increasingly replacing copper with cheaper aluminium in vehicle wiring as rising metal prices push the industry to lower costs and improve efficiency.
Global automakers including Ferrari and BMW are increasingly switching from copper to aluminium in vehicle wiring as rising copper prices push manufacturers to look for cheaper alternatives.
According to Reuters, the step follows similar moves by Tesla and several Chinese EV makers, reflecting a wider industry shift driven by cost pressures and the rising demand for lightweight materials in electric vehicles.
Copper prices hit record growth earlier this year, touching nearly $15,000 per metric ton, making aluminium a more attractive option. aluminium currently costs around $3,100 per ton, or roughly one-fourth the price of copper.
Ferrari said it began using aluminium wiring in its 296 hybrid sports car last year and has since increased its use to other models, including the newly launched electric vehicle, Elettrica. The company said the move reduces total wiring weight by up to 20%.
BMW said it has steadily expanded the use of aluminium conductors across hybrid and EV models. Analysts say lighter aluminium wiring improves EV range, while lower material costs help automakers protect margins.
However, experts note aluminium remains less efficient than copper and may not suit all applications despite its cost advantage.
