The invention relates to a method for forming an aluminium composite material which has a core alloy made from an aluminium alloy of type AA5xxx or AA6xxx and at least one outer aluminium alloy layer provided on one or both sides, wherein the aluminium composite material is formed and the outer aluminium alloy layer provided on one or both sides has a yield strength Rof 25 MPa to 60 MPa in the soft or solution-annealed state. The method enables the production of large-surface, heavily formed aluminium alloy sheet metal parts, in particular also in outer skin quality.

Aluminum composite material and forming method

Embodiments relate to a device for performing a bending test having a base plate, counter bearings connected via the base plate, bearing blocks which in each case comprise a support for applying a bending sample, and a bending punch or a bending rail for exerting a force on a bending sample. The distance of the supports can be set precisely and in a force resistant manner by abutting the counter bearings and the bearing blocks against each other via contact surfaces inclined to the base plate. Further provided is a method for performing a bending test using a device according to the invention, in the case of which a bending sample is applied on the supports and in the case of which a force is exerted between the supports on the bending sample.
