The current impetus in aluminum alloy development for automotive applications has been mainly due to government legislation requiring automotive manufactures to significantly improve fuel efficiency of new vehicles. Aluminum alloys are ~65% lighter than ferrous alloys, and therefore have a great potential to be used in many automotive applications. Another focus of lightweighting in the industry is to develop advanced, low-displacement, high power density engines. This trend frequently demands increased operating temperatures and pressures for powertrain components, therefore making many currently used alloys unfit for their respective applications due to, for example, insufficient strength. Both trends lead to demand for higher-performing alloys and the need to develop and test new alloying systems.

目前汽车用铝合金发展的动力主要是由于政府立法要求汽车制造商显著提高新车的燃油效率。铝合金比铁合金轻约65%，因此在许多汽车应用中具有很大的潜力。轻量化的另一个重点是开发先进、低排量、高功率密度的发动机。这种趋势经常要求动力总成部件的工作温度和压力增加，因此，由于强度不足等原因，目前使用的许多合金不适合各自的应用。这两种趋势导致对高性能合金的需求以及开发和测试新合金系统的需求。
