Automotive - Accelerating Efficiency
Aluminum is the fastest, safest, greenest and most valuable way to reduce weight, improve vehicle performance, increase fuel efficiency, extend battery range and reduce emissions. Aluminum makes cars better - and more so!
As the industry prepares for a wave of electric powertrains and EV platforms, aluminum is the first choice for many automakers because of its ability to reduce vehicle weight - extending vehicle range and offsetting the impact of heavy components such as EV batteries.

Where is aluminum used in cars?
Alloys offer a variety of benefits including strength, corrosion resistance, impact resistance, formability, weldability and electrical conductivity to meet the safety and performance needs of the industry.
Automotive Body
Aluminum alloys used in automotive bodies require excellent corrosion resistance, surface finish, and machinability. Common alloys include 3105, 5005, 5083, 5182, 6016, and 6181.
- Body parts: hoods, quarter panels, fenders, bumpers, spoilers, roof racks, grilles, hoods, decklids, headers, pillars, rims and hubcaps, trunks, valances.
- Doors: central locks, hinges, latches, handles.
- Windows: motors, sunroofs, sunroof rails.
Automotive Electronics
Although aluminum has a lower electrical conductivity than copper, its low weight makes it ideal for automotive electronics.
1350 alloy is commonly used in audio and video equipment, backup cameras and displays, power systems, instruments and gauges, ignition systems, lighting and signals, sensors, switches, and wires in wiring harnesses.
Automotive interiors
Aluminum alloys such as 1100, 3105, and 5052 are used in automotive interiors for floor components and parts, automotive seats, insulation materials, air conditioning, bearings, and hoses, offering a lightweight, durable, and efficient solution that meets customer demands for performance and comfort.
Powertrain and chassis
These complex components require high strength, fatigue resistance and weldability. Common alloys are 2024, 4032, 5052, 5005, 5083, 6016, 6082 and 6111.
These complex components require high strength, fatigue resistance, and weldability, with common alloys including 2024, 4032, 5052, 5005, 5083, 6016, 6082, and 6111, making them ideal for braking systems, electric powertrain components, engine components, engine cooling systems.
Aluminium in cars has the lowest overall carbon footprint
More than 95% of automotive aluminum scrap (more than 1.5 million tons per year) is recycled for reuse. To put it in perspective: recycling one ton of aluminum saves the energy equivalent of 21 barrels of oil.Quick Quote
Research from the U.S. Department of Energy’s Oak Ridge National Laboratory found that aluminum-intensive vehicles can reduce lifecycle energy consumption by up to 20% and reduce CO2 emissions by up to 17%.
