Aluminum Production — Ultrasound Reliably Detects Inclusions

Thanks to its physical properties, aluminum plays a major role in the circular economy and achieving climate neutrality. High material quality is crucial during processing, as any contamination present in the aluminum during smelting diminishes the quality of finished components. Unlike existing methods of analysis, the ultrasound-based AloX measuring system from the Fraunhofer Institute for Nondestructive Testing IZFP can detect existing inclusions not only reliably but also quickly and at low cost. The team of researchers was presented with the Joseph von Fraunhofer Prize for 2025 for developing this innovative tool.
