Jede dieser Legierungen hat ihre Vorzüge, indem gewisse mechanische Eigenschaften wie beispielsweise die Festigkeit optimiert sind, allerdings zumeist unter Inkaufnahme einer Verschlechterung anderer Eigenschaften wie beispielsweise des Umformvermögens.Alloys known in practice which are used for the production of body panels for the automotive industry are described in DE-A-27 14 395, US-A-4 082 578 and EP-B-0 259 232. Each of these alloys has its advantages in that certain mechanical properties such as, for example, the strength are optimized, but usually with the acceptance of a deterioration in other properties such as, for example, the formability.
