  • An economic evaluation of aluminium-based lightening in current and future generations of passenger cars - good news for aluminium [Elektronski vir]
    Kevorkijan, Varužan
    The use of aluminum in passenger cars has rapidly increased in the last 20 years. Only since 1991, the use of automotive aluminum has doubled and is expected to double again by 2005. However, it is ... very important to emphasize that today's vehicles are not aluminum intensive at all, consisting of, on average, 6% of aluminum alloys and, according to current predictions, vehicle producers in 2005 will still use 50% of steel as the main constituent in cars. At the first glance, one could suggest that some well influential protagonists of aluminum just like to play games with percentages. In this respect, we will show here in numbers why aluminum will be the great winner in the car industry. Current expectations are that the average European consumption of aluminum in cars in 2005 will be between 100 and 140 kg per vehicle, which is today's amount of aluminum in North American cars. Just as an illustration, today's average consumption of aluminum in European cars is around 65 kg per car. In contrast, the most intensive use of aluminum in a passenger car approximates to 295 kg, defining the present target for further material substitution. The basis for these trends lies mainly in the expandingauto industry which, under market, ecological, safety and other pressures, has to maintain its development towards lightening and "aluminum intensive" vehicles. To be clear, in our opinion lightening does not necessarily means "aluminum intensive", as recently demonstrated by the ULSAB (Ultralight Steel Automobile Body) project. It is well known that a 10% reduction in vehicle weight yields an approximately 5.5 % improvement in fuel economy. From the economic point of view this clearly means that the real customer is going to pay for the advanced lightening of his future vehicle no more than exactly the amount of money saved through the improved fuel economy. As will be demonstrated, aluminum, in comparison with steel, is an absolute winner in this important economy contest.
