The analysis concluded the specimen is a conventional near-eutectic aluminum-silicon cast alloy (approximately 86% Al, 12% Si with minor elements), consistent with common industrial applications such as engine components. Microstructural features including large grains, casting pores, and silicon precipitates indicate standard slow-cooling mold casting rather than advanced or exotic manufacturing. No abnormal gamma emissions or other anomalous properties were found. AARO's supplement provides historical context confirming the material matches well-documented terrestrial aluminum alloys and is inconsistent with claims of advanced UAP-derived technology.
