Short answer: Cars and EVs lean on advanced high-strength steel for crash-critical bodies, aluminium for closures and battery enclosures, and copper for motors and busbars, with grade chosen for weight, crash performance and electrical conductivity rather than habit.
At a Glance
Lightweighting the Body
Advanced high-strength steels (DP, TRIP, martensitic) cut mass while holding crash performance, while aluminium closings and battery boxes add further savings; the trade-off is in our Steel vs Aluminium e 5052 vs 6061 guides.
Aluminium for Closures and Boxes
6061 and 6082 extrusions form hoods, doors and battery enclosures because they are light and easy to join; the family is in our Extrusion Profiles Guide e 6061 vs 7075 comparison, with strength numbers in our Confronto di forza.
Copper for the Powertrain
EV motors and busbars depend on high-conductivity copper; the busbar choice is in our Busbar Copper vs Aluminium and the wire angle in our Copper vs Aluminium Wire guides.
Fatigue and Durability
Suspension and chassis parts see millions of cycles, so fatigue limits gate the choice; our Fatigue Guide e Titanium vs Steel comparison explain the criteria, and titanium earns its place where weight matters most.
Sourcing for a Program
OEMs and Tier-1 suppliers bundle steel, aluminium and copper into scheduled programs with PPAP and traceability; our How to Choose a Metal Supplier covers the commercial side.
