Interactions and contradictions between academic investigations and industrial material development are demonstrated. The structure of AlMgSi with optimal properties was understood recently after its 50 years industry scale production. The applicable SiC tool production is underway despite of the lack of the phenomena controlling its skeleton structure and binding mechanism Biaxial polyethylene (PE) foils are far widely used but its difficult partly crystalline oriented lamellar structure could be just nowadays descripted. These examples seem to demonstrate the priority of the purpose and profit oriented material design.
