Short answer: Automotive structures lean on advanced high-strength steel for crash zones and aluminium 6xxx / 5xxx for body and battery-enclosure panels; EV packs add aluminium trays, copper busbars and sometimes magnesium brackets. The selection balances crash performance, weight, conductivity and corrosion in a tightly controlled production environment.
At a Glance
Body and Crash Structure
Advanced high-strength steel (DP, TRIP, press-hardened) carries crash loads at low mass, supported by our HSLA Steel Guide ve Formability Guide. Hang-on parts and closures move to aluminium to save weight — stocked by our Aluminium Sheet Supplier.
EV Battery Enclosures
The pack enclosure must be light, stiff and capable of managing a crash and thermal event. Aluminium 6061 and 5052 trays and lids dominate; sealing and corrosion care follow our Metal Surface Treatment Guide, and weld quality is checked per our Welded Tube Guide.
Conductive and Cooling Parts
Busbars and terminals use copper (our Copper Busbar Guide) and copper-nickel for coolant lines; conductivity ranking is in our Electrical Conductivity Guide. Enclosure cooling plates exploit aluminium’s thermal conductivity from our Thermal Conductivity Guide.
Lightweighting and Joining
Magnesium AZ31B trims bracket and housing mass; joining mixes welding, adhesive bonding (our Joining Methods Guide) and mechanical fasteners (our Gasket Guide). Each joint is verified by the NDT methods in our NDT Guide.
