Aluminum in Electric Vehicles: How the EV Transition Is Reshaping Demand

Aluminum Content: ICE vs EV vs Electric Truck

Why EVs Use More Aluminum Than ICE Vehicles

Plug-in hybrids and full battery EVs use 25 to 27% more aluminum than a comparable ICE vehicle, driven primarily by battery enclosures and the structural reinforcement required around high-voltage systems (CRU Group). The battery pack in a long-range BEV is both the heaviest single component in the vehicle and one of the most structurally demanding: it must carry the floor load of the vehicle, protect cells from impact, seal against moisture and coolant ingress, and maintain thermal management. Aluminum solves all of those requirements at roughly 40% lower weight than an equivalent steel design. Battery electric light trucks are expected to average over 644 pounds of aluminum content by 2030 - nearly double the aluminum content of an equivalent diesel truck (Aluminum Association, 2023).

Battery Enclosure Alloy Selection

All currently available long-range BEVs with 250-plus mile range use aluminum as the primary battery enclosure material. The dominant structural alloys are 6061-T6 and 6082-T6 for extrusions and machined components, with 5000 series alloys (5052, 5083) used where coolant circuit corrosion resistance is the primary requirement. The 6000 series offers good strength, excellent machinability, and consistent anodizing response for sealing surfaces. The 5000 series is preferred where exposure to glycol-based coolants under sustained contact is a design condition - the magnesium content provides better chloride and organic acid resistance than silicon-magnesium 6xxx in some formulations. Both alloy families require cut-to-size plate as a starting material for battery tray machining.

Global Demand Forecasts

The International Aluminium Institute projects global aluminum demand to rise 40% by 2030, from 86.2 million tonnes in 2020 to 119.5 million tonnes in 2030. EVs alone are expected to account for approximately 63% of new aluminum demand in transport, adding an estimated 7.4 million tonnes of annual consumption by 2030. The NEV (new energy vehicle) aluminum market specifically is estimated at $15 billion in 2025 and projected to reach $50 billion by 2033 at an 18% compound annual growth rate (Archive Market Research, 2025). China, Europe, and North America together represent approximately 93% of that growth.

What This Means for Plate Buyers

For buyers sourcing plate for EV battery enclosures or structural components, the most relevant implication is that 6061 and 5000 series plate in common thicknesses (0.125 to 0.500 inch) is experiencing rising demand from automotive alongside existing aerospace and industrial demand. Lead times for common sizes may tighten as EV production ramps. DFARS requirements do not apply to automotive programs, but origin documentation is increasingly requested by OEMs for supply chain risk and sustainability reporting purposes. Establishing stocking supplier relationships for common sizes reduces exposure to spot market volatility.
