Vehicle makers are accelerating their move from other materials to aluminium in a bid to produce lightweight vehicles that are more cost effective.
According to a survey of North American automakers, there is continued growth in the use of aluminium which is expected to reach a high of 343lbs per vehicle in 2012 – up five per cent from 327lbs per vehicle in 2009. This number is expected to expand even further to reach 550lbs by 2025.
The survey reports that aluminium use has increased every year for nearly 40 years and in the longer term it should double its share of the average automotive materials mix to 16 per cent. With the Obama administration considering stricter fuel economy regulations, carmakers are expected to lower the overall weight of a vehicle by 400lbs – with aluminium expected to play a key role.
It is now established as the leading material in powertrain and wheel applications and is quickly gaining market share in areas such as bonnets (hoods), boots (trunks), doors and bumpers.
In addition, the survey examined average aluminium content among North American automakers and found that General Motors is the content leader at 366lbs per vehicle. Some of the latest models featuring above average aluminium content include: the Chevrolet Malibu, Cadillac GTS, Chrysler C, Fiat 500, Ford Explorer, Ford Focus, Ford Escape, Honda Accord, Honda Civic/CR-V, Lincoln MKZ, Nissan Altima and the Toyota Avalon.
