Titanium Güte 23 (Ti-6Al-4V ELI): Medical Implant Güte für Orthopedics
ASTM F136 / B348 · Published: 2026-06-02 · Updated: July 2026
Grade 23 ELI has tightly controlled oxygen (75 MPa√m). For hip stems, knee femoral components, spinal pedicle screws, dental implants. Osteointegrative — bone adheres directly to TiO2 surface without fibrous tissue.
Güte 23 ELI hat tightly controlled oxygen (<0.13%) for maximum fracture toughness (KIC >75 MPa√m). Für hip stems, knee femoral components, spinal pedicle screws, dental implants. Osteointegrative — bone adheres directly zu TiO2 surface ohne fibrous tissue.
