According to the lastest survey by Ducker Worldwide on the applications of aluminium in the European automotive industry, during next decade the content of light alloys in cars is likely to increase by up to 30%. This increase mainly derives from a higher use of rolled products for bodyworks, whose expected increase exceeds 110%. The reasons for this extraordinary development in the use of aluminium in the transport industry relates to the need of reducing vehicle weight for lower emissions and lower fuel consumption.
Ducker data indicate that within 2025 the current 150 kg of light alloy content per vehicle will rise to almost 200 kg. The comparison of the evolution of the different types of aluminium semis used in vehicles between 2012 and 2016 shows that castings still prevails (99.5 kg per vehicle in 2016) but have been dropping by 8% in relative terms over the last four years while FRPs (27.2 kg per vehicle in 2016) – used for doors and other parts of the bodywork, heat exchagers and miscellaneous components – have dramatically increased. The share of extrusions and forgings remains the same at 16.8 kg per vehicle.
