Safety components made of aluminum have the highest requirements in vehicle design. Leichtmetallkompetenzzentrum Ranshofen and Hammerer Aluminium Industries Extrusion have improved the crash properties of an extruded profile by means of alloy modification and geometric adaptation of the cross section. An increase in energy absorption and reduction of cracking has been achieved.

Crash Properties of Aluminum

In recent decades, aluminum has become more and more important as a lightweight material. However, further improvements of the properties are still essential to meet the increasing demands in the field of lightweight design in the future. This article describes how the crash characteristics of an extruded two-chamber profile were improved. The profile is used as a safety component in vehicles in the load-bearing structure of the body. In order to increase the energy absorption of the profile in the event of an impact, the yield strength of the material is increased. While this may...
