Structure component e.g. A-column, for body of passenger car, has three connecting plate parts that are made of aluminum alloy of specific alloy class and processed under specific heat treatments, respectively

摘要

The component (10) i.e. connecting plate (12), has three connecting plate parts (14, 18, 23) made of an aluminum alloy of the alloy class 7000. The connecting plate parts are processed under T-6 heat treatment, T79 heat treatment or T76 heat treatment, T4 heat treatment or T73 heat treatment, respectively. Two of the connecting plate parts are spaced from each other under shifting of other connecting plate part. An elongation limit of the connecting plate parts are 400 Mega Pascal (Mpa). An independent claim is also included for a method for manufacturing a structure component.
