The noble metal content in both alloys is higher than 95 %. Less than 1 % difference in base metal concentration. ### Conclusion The major constituent (Au) and the noble metal content are similar. Even the residuals are the same elements. The very high noble metal content suggest an effective biocompatibility Image /page/0/Picture/22 description: The image shows a logo with the text "TUV CERT" stacked on top of each other.
