6. Conclusions
The review of the above significant parameters and attributes gives us a good impression on the overall potential, prospects and efficacy of aluminum alloy as a befitting and competitive substitute to conventional steel for producing environment friendly, reliable and affordable automobiles. We understand that with increasingly stringent vehicle emission and fuel efficiency regulations and concepts like the 1 Liter cars (mini cars) and other alternative NZEVs (Near Zero Emissions Vehicles, EPA) coming up, aluminum is an inevitable choice. It is important to note that even after having the qualities to surpass steel on all possible fronts; aluminum could only make very limited headway (only 8-10% use) into the automotive industry at present and a projected 12-20% rate of use in future. This is substantially lower compared to the 80% and above rate of use for steel and this situation demands immediate efforts from the vehicle manufacturers, aluminum producers and suppliers and other stakeholders. Nevertheless, we are now confident that this present status of aluminum in the automotive sector is destined to change for the better in the coming years and it is possible that a complete role reversal between steel and aluminum, at least in the automobile sector will occur in the not too distant future.

上述重要参数和属性的评论使我们对整体潜力的好印象，前景和铝合金效果作为生产环境友好传统的钢与竞争的替代品，可靠和负担得起的汽车。我们知道，日益严格的汽车排放和燃油效率规定和概念如1升汽车（微型车）和其他替代nzevs（近零排放车辆，EPA）即将到来，铝是一种必然的选择。需要注意的是，即使有超过钢在所有可能的方面素质的重要；铝只能非常有限（只有8-10%使用）目前和预计的12-20%的使用率在未来进入汽车行业。这是大幅降低相比，80%和以上的钢的使用率，这种情况要求车辆制造商，铝生产商和供应商和其他利益相关者的直接努力。不过，我们现在有信心，铝在汽车行业的现状是注定要改变在未来几年更好，这是可能的，一个完整的钢铁和铝之间的角色逆转，至少在汽车行业将发生在不太遥远的未来。
