Medical Titanium

Medical Titanium — Engineering & Procurement Topic Overview (5 Articles)

Medical and dental titanium requires the highest level of metallurgical cleanliness, interstitial impurity control, and lot-to-lot microstructural uniformity in the titanium industry. Permanent surgical implants—such as spinal pedicle screws, femoral hip stems, trauma bone plates, and dental implant fixtures—are predominantly manufactured from Extra Low Interstitial Grade 23 (Ti-6Al-4V ELI per ASTM F136 / ISO 5832-3) or unalloyed cold-worked Grade 4 (ASTM F67 / ISO 5832-2).

For CNC Swiss automatic lathe machining and CAD/CAM dental milling, bar and disc stock must combine A1 fine equiaxed alpha-beta microstructure with centerless-ground ISO h6/h7 diameter tolerances and straightness <= 0.5 mm/m.
