    • The invention relates to an automobile body or a component of an automobile body comprising at least one first sheet metal component consisting of a first aluminium alloy (A) and at least one second sheet metal component consisting of a second aluminium alloy (B). According to the invention, the first and the second aluminium alloy are of the AlMgSi type and the sheet metal consisting of the second aluminium alloy (B) comprises a significant fraction of the elements Mg and Si that are required to obtain thermal hardening in a solid solution, in the form of deposited Mg2Si and/or Si particles, in order to prevent thermal hardening prior to the thermal hardening of the body or body components. In addition to enabling the common recycling of process scrap metal during the production of the different components and the simple scrap metal recycling of body parts in old cars, the inventive automobile body provides improved impact protection for pedestrians, in comparison to solutions in prior art, by reducing the hardening capacity of the second components during the thermal hardening of the body that occurs in a paint baking cycle.
    • 本发明涉及一种汽车车体或汽车车身部件,其特征在于包括由第一铝合金(A)和至少一个由第二铝合金(B)组成的第二金属板部件组成的至少一个第一金属板部件。 根据本发明,第一和第二铝合金是AlMgSi型,并且由第二铝合金(B)组成的钣金包括在固体中获得热硬化所需的元素Mg和Si的重要部分 溶液,以沉积的Mg2Si和/或Si颗粒的形式,以防止在身体或身体成分的热硬化之前的热硬化。 除了在生产不同部件的过程中废金属的共同再循环以及旧车身体零件的简单废金属回收之外,本发明的汽车车身与现有技术的解决方案相比,为行人提供了改善的冲击保护, 通过在涂料烘烤循环中发生的身体的热硬化期间降低第二组分的硬化能力。
