Titanium body jewelry
What Titanium materials are best for body jewelry? My articles at https://jewelry.piercing.org/ and https://brnskll.com/shares/titanium-standards-why-not-g23/ explain that the two most effective Titanium standards are alloyed ASTM F136 and pure ASTM F67, the most common being the former as it is stronger, harder and easier to polish. Both are used for permanent surgical implants.
