Lightweighting drives the shift to aluminium
Replacing steel with aluminium can cut the weight of a body or chassis part significantly. For combustion vehicles that means lower fuel use and emissions. For electric vehicles it offsets the heavy battery pack and adds range.
Aluminium also absorbs crash energy well when designed as extruded crush rails, conducts heat away from batteries and power electronics, and is easy to recycle at the end of the vehicle's life.
Where aluminium is used
Body-in-white and closures
5xxx sheet for inner panels and 6xxx sheet for bonnets, doors and boot lids.
Crash management
Extruded bumper beams and crush boxes in 6xxx and 7xxx alloys.
Thermal management
Radiator, condenser and cooling plate materials, including brazing sheet.
Chassis and suspension
Forged control arms and knuckles in 6061 and 6082.
Wheels
Cast and forged wheels for weight saving where it matters most.

Automotive & EV questions
Why are EV battery trays made of aluminium?
Aluminium is light, stiff when extruded into hollow sections, conducts heat away from the cells and resists corrosion, which makes it ideal for battery enclosures.
Which aluminium is used for car body panels?
6xxx alloys such as 6016 for outer panels, because they harden during paint baking, and 5xxx alloys such as 5182 and 5754 for inner panels.
