Iterative label spreading (ILS), an unsupervised machine learning approach, was used to identify the different classes of Al alloys, drawing from a specifically curated dataset of 1154 Al alloys (including alloy composition and processing conditions).  Using ILS, eight classes of Al alloys were identified based on a comprehensive feature set under two descriptors.
