Titanium Properties
Grade 23 is also known as Ti6Al4V ELI or simply Ti 6-4 ELI. ELI stands for Extra Low Interstitials. Titanium Grade 23 is very similar to Grade 5 except that Grade 23 has less oxygen, nitrogen and iron. This makes the alloy more ductility and better fracture resistance (but slightly less strength) than Grade 5.

Suitable For
TiGr5 Eli is used in biomedical applications such as surgical instruments, orthopedic implants, and is the preferred grade for marine and cryogenic applications, and some important aerospace components.
Remarks
Biocompatibility: Excellent, especially when direct contact with tissue or bone is required.
Surface treatments such as nitriding and oxidizing can improve the surface wear properties.
