Titanium is a metal that generates a very light layer of almost negligible oxide, a kind of metal protective film, stable and absolutely non-toxic. If a titanium product is scratched with a sharp object or scouring pad, this outer layer is affected and a scratch is seen. This oxide layer is recreated in that area, although it is not visible to the naked eye, it is one of the characteristics of titanium in contact with air and that reinforces its biocompatibility.
