Abstract
The demand for automotive sheet shows the highest growth rates in the aluminium industry . Currently, the main alloys are from 5.xxx and 6.xxx series with a variety of approx. 40 different specifications. Such a mixed scrap quality cannot be used in an efficient way in cast houses, due to the divergent Mg and Si concentrations. Additionally, the ratios between 5.xxx and 6.xxx scrap are unpredictable. Today, the only technical possibility to distinguish between these alloys is sensor based sorting using LIBS . Such a sorting machine has to produce two sorting fractions, which both fulfill the requirements of the new wrought alloys. In this case a high sorting efficiency is mandatory. First results show a purity of the sorted fraction above 95% as well as a high recovery of the sorted material also above 90%.
