Ferrari and BMW Accelerate Shift to Aluminum Wiring, Raising Attention on Copper Substitution
Ferrari and BMW are introducing aluminum wiring into new vehicle models, joining Tesla and several Chinese EV manufacturers in replacing part of their copper wiring with aluminum. Aluminum costs roughly one-quarter as much as copper and offers significant weight savings, helping improve vehicle efficiency and driving range. Aluminum substitution is expected to affect around 2% of global copper demand in 2026, with the potential to replace as much as 6% of annual copper demand by 2030 if copper prices remain structurally high. Market participants believe electric vehicles, power cables and home appliances will be the main sectors driving aluminum substitution, although copper is expected to retain its dominant position in applications requiring superior electrical conductivity and performance.
