New study: Aluminum content increased 20% since 2016

Aluminum content in cars up 20% in the last three years

A new study estimates the average aluminum content of European-produced cars will reach nearly 180 kg in 2019, meaning a 20% increase since 2016. The study, the third edition of the Aluminium Content in Cars from DuckerFrontier and commissioned by the European Aluminium industry association, also forecasts the average aluminum content to further increase to almost 200 kg per vehicle by 2025.

The positive outlook and uninterrupted aluminum growth is largely attributed to aluminum’s role in lightweighting cars and as an enabler of electromobility.

Carmakers’ preference for aluminum is largely linked to its lightweight nature, making all cars more energy-efficient, no matter if it is a gas, diesel or electrified vehicle. Due to its inherent strength and its excellent ability to absorb crash energy, well-engineered aluminum car parts can be made safer than steel but up to 50% lighter. Lighter cars substantially contribute to reducing CO2 emissions and improving fuel efficiency.

“Aluminium is a true enabler of electro-mobility. The combination of aluminium sheet, extrusions and castings bring perfect solutions for electric vehicles. Both as protection of the batteries and to reduce the weight of the vehicle to increase its performance or range,” said Dieter Höll, chairman of the Automotive & Transport Board at European Aluminium.

The study points to electrification as one of the main drivers for the future growth of the aluminum content in all product forms. Battery boxes, electric motor housings, but also body closures and body structures are highlighted as key applications for increased aluminum penetration in the future. Depending on the car segment, the average aluminum content per vehicle is forecasted to increase from at least 2.9 kg by 2025 in the A-segment and up to 38.0 kg in the D-segment.
