The aim of the LOEWE research cluster "ALLEGRO - high-performance components made of aluminum alloys" is to develop new, efficient processes for the integrated shaping and heat treatment of wrought aluminum alloys through generally transferrable, quantitative descriptions of relevant causal relationships. Because the key to using the full lightweight construction potential of aluminum lies in increasing the geometric and microstructural complexity of products, which has not yet been technologically implemented. 

LOEWE-ALLEGRO riddle: 

Where are high-strength aluminum alloys used? 

Additional question: Which alloying element is required to make aluminum high-strength? 

a) Zn 

b) Mn 

c) Si 

Have fun and good luck with the solution!
