ALUMINIUM - the car makers metal of the year?
With the launch of the A2, Audi AG introduced the first vehicle in the world to have a volume-built all-aluminium body. In 1996, series production of the A8 began. The A8 is the first luxury limousine made of aluminium, and the Audi plant in Neckarsulm produces 20000 vehicles a year. The A8 combines high strength with low weight. At onli 1690 kilos, the A8 3.2 is the lightest car in the luxury class. The third-generation Audi Space Frame now has fewer makes it easier to build the car in large quantities.
other car makers are also starting to take aluminium seriously. As engine sizes have increased, cars have bacome more top-heavy. Using aluminium for the bonnet and front wings helps to get a better weight distribution between front and rear axles. Anower advantage of auminium is that it is cheaper to recycle than steel. This will be an important consideration in the future when the EU introduces tougher recycling regulations.
But there are drawbachs to using aluminium. Replacing steel with aluminium is expensive; an aluminium body cost twice as much as a steel one. Not onli are aluminium production rpocesses expensive, they are also difficult to implement. Because aluminium is more brittle and tears more easily than steel, it can onli be formed when it is in an unhardened state. Furthermore, the aluminium used for the outer parts of the car, such as the wings and the doors, needs to be thicker than steel because it doesnt have the same stiffness. the dent-resistance of aluminium is also than that of steel.
On the plus side, aluminium doesnt rust like steel, and in car crashes it has a higher energy absorption rate, which increases the cars active saferty.

铝-汽车制造商的金属的一年？
A2的推出，奥迪公司推出的第一个汽车在世界上有一个内置全铝体体积。1996，A8系列的生产开始。的A8是铝做的第一辆豪华轿车，奥迪和内卡苏姆工厂每年生产20000辆。A8的结合低重量，高强度。在只有1690公斤，3.2的A8是豪华级轻的车。第三代奥迪空间框架现在较少，使得它更容易建立大量的汽车。
其他汽车制造商也开始采取铝严重。随着发动机的大小增加，汽车已成为更重。采用铝盖和前翼可以得到一个更好的重量分布在前轴和后轴。anower优势auminium是循环比钢便宜。这将是一个重要的考虑因素在未来当欧盟介绍了更严格的回收条例。
但有drawbachs使用铝。以铝代钢是昂贵的；人体铝作为钢成本的两倍。不单单是铝生产过程昂贵的，他们也很难实现。因为铝是较脆，比钢更容易流泪，它只能被形成时，它是在一个未硬化状态。此外，用于汽车的外部分的铝，如翅膀和门，要比钢由于它具有相同的刚度。铝的抗凹性也比钢。
在另一方面，铝和钢锈一样，在车祸中具有更高的能量吸收率，增加了汽车的主动安全
