Metal implant

Metal implant on the right hip Alberto

The average composition is estimated at about 25% of copper for 50% of silver.

The composition of this sample matches perfectly with the typical compositions listed for Pre-Columbian era objects made from a copper-silver alloy. The observable micro-structure in topographic imaging seems to indicate that the source object was designed by stamping coppersilver alloy leaflets by cold-threshing, a technique also listed for many Pre-Columbian objects design.

Concerning the implant bio-compatibility made from such an alloy, given the chemical activity of copper and silver depending on the context (pH, …), the histological consequences on a living organism would be uncertain and requires the advice of a specialist.
