Relationship between G23 Titanium and ASTM F136

G23 titanium is a material grade designation, ASTM F136 is the specification for the alloy to be used for surgical implants.
G23 titanium alloy that meets ASTM F136 specifications is used for surgical implants or body jewelry that come into contact with the human body.ASTM F136 is a refined version of Grade 23 Ti6Al4V ELI.
For human body contact as surgical implants or body jewelry, ensure that the titanium alloys provided by your raw material supplier meet the F136 or F67 standards and are finished according to the F2791 and F86 standards. When it comes to body jewelry, only the ASTM F specifications for surgical implant materials are relevant. F136 and F67 are the only two currently in large scale jewelry production. The more specific F136 standard is the standard titanium alloys should meet for use in body jewelry.This will be to your advantage, and for your customers.
