This research dealt examining, analysis and treatment of a silver - copper belt, it exhibited in Agriculture Museum in Cairo. This research aims to study the ancient silver alloy; because of the successful examination and analysis helps in the treatment of old metal objects and then maintain them. The analysis of archaeological objects requires simultaneously nondestructive (the objects are unique and precious), versatile (samples with different geometry), sensitive (trace elements are often important) and multi-elemental methods. In this paper, scanning electron microscopy (SEM) employed to diagnose the characteristic morphology and environmental effects of the silver-copper object. X- Ray diffraction (XRD) used to identify the mineralogical composition of samples, inductively coupled plasma optical emission spectrometer (ICP) used to determine the accurate elemental composition of the silver-copper object. The results obtained by this research showed that the alloy containing about 22% silver, 65% copper, and it covered with copper corrosion products, these results represent the correct diagnosis, which will help us to understand the fabrication of ancient silver-copper alloy, which is still needed more studies.
