A method for producing a structural sheet metal component formed from an aluminum alloy for a motor vehicle includes providing an aluminum sheet blank in a state Tor Tor Tor T, heating the aluminum sheet blank to a heating temperature between 100&#xb0; C. and 450&#xb0; C., forming the aluminum sheet blank to a structural sheet metal component, and heat post-treatment of the formed structural sheet metal component.

Method for producing a structural sheet metal component, and a structural sheet metal component

A motor vehicle sheet metal molding of the invention is produced by hot forming from a metal sheet composed of an aluminum alloy which cannot be precipitation hardened, which contains at least magnesium and optionally manganese in addition to aluminum as alloy component. The motor vehicle sheet metal molding after forming has, at least locally, degrees of deformation which are above the forming limit curve of the aluminum alloy at room temperature. To produce the motor vehicle sheet metal molding, the metal sheet is heated at least locally to a temperature in the range from 200&#xb0; C. to 400&#xb0; C. over a period of from 1 to 60 seconds. The heated metal sheet is subsequently placed in a forming tool of a forming press and formed to produce the motor vehicle sheet metal molding.

Sheet metal molding for motor vehicles and process for producing a sheet metal molding for motor vehicles

A bumper for a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame. A crash box is incorporated between the cross member and the side rail, with set bolts being provided to join the crash box to the cross member in the absence of prepunching.

In a method of making a subframe of a motor vehicle profile elements made of hollow sections of steel are placed in a casting tool. Subsequently, aluminum material is filled into the casting tool to casting around the profile elements so as to form plural cast nodes on the profile elements in spaced-apart relationship.

A crash box for installation between a bumper beam and a side rail of a motor vehicle includes an outer tube, and an inner tube which is held inside the outer tube, with the outer and inner tubes being movable in relation to one another. At least one of the inner and outer tubes is provided with a coat of varnish at least in a contact area between the outer pipe and the inner pipe.
