Titanium is a metallic element well known for its resistance to corrosion, almost equal to that of platinum, and for its high strength-to-weight ratio, in fact titanium weighs half as much as steel and is twice as resistant. Ti6AL-4V grade titanium (ASTM F-136) finds wide application in the biomedical field for the production of prostheses, thanks to its excellent biocompatibility with the human organism, due to the absence of toxic components. In the world of piercings, titanium is ideal for both the first hole and those that have already healed. It is available mirror polished or with anodized colors.
