Small metal fragments were found in the tomb of the Wari culture elite (Castillo de Huarmey, Peru). These objects were subjected to chemical analysis using a scanning electron microscope with energy‐dispersive X‐ray spectroscopy and field emission (FE‐SEM‐EDS), an electron microprobe analyser with field emission (FE‐EMPA) and X‐ray diffraction (XRD) analysis. Chemical composition analysis showed that four different alloys were used to make copper objects. Two different alloys were found in silver alloys. A comparative analysis was made of the artefacts of other cultures from the Middle Horizon Period. They differ in their chemical composition.

来自Castillo de Huarmey（秘鲁）的金属小碎片的化学组成：使用FE-SEM-EDS，FE-EMPA和XRD在微观区域进行化学分析

在瓦里文化精英墓（秘鲁卡斯蒂略·德·哈梅基）中发现了小的金属碎片。使用具有能量色散X射线光谱和场发射（FE-SEM-EDS）的扫描电子显微镜，具有场发射（FE-EMPA）和X射线衍射（XRD）的电子微探针分析仪对这些物体进行化学分析） 分析。化学成分分析表明，使用了四种不同的合金来制造铜制物体。在银合金中发现了两种不同的合金。对中地平线时期其他文化的文物进行了比较分析。它们的化学组成不同。
