Titanium Ti-6Al-4V ELI for Dental Implant
Premium Grade 23 Ti-6Al-4V ELI titanium pucks are specifically engineered for high-precision dental laboratory milling.
Certified to the strict ASTM F136 surgical implant standard, this material guarantees ultra-high purity and bio-safety.
Compared to standard Grade 5, its Extra Low Interstitial (ELI) composition delivers significantly higher fracture toughness and fatigue resistance.
It provides the ideal balance of strength and flexibility for demanding implant-supported restorations.
Key Chemical Composition
Grade 23 strictly limits interstitial elements to achieve superior ductility and crack resistance compared to standard Grade 5:
- Oxygen (O): ≤ 0.13% (vs. ≤ 0.20% in Grade 5)
- Hydrogen (H): ≤ 0.015%
- Carbon (C): ≤ 0.10%
Application: Ideal for complex and thin-walled frameworks—such as full-arch All-on-X bars—while its smoother material removal extends milling bur longevity.
Specifications
Available Heights: 10 mm – 25 mm
Diameter: 98 mm standard puck (with shoulder step)
Grade 23 vs Grade 5 Titanium Composition & Properties
| Property | Grade 5 (Ti-6Al-4V) | Grade 23 (Ti-6Al-4V ELI) |
|---|---|---|
| Industry Standard | ASTM B348 / ASTM F1472 | ASTM F136 (Surgical Implant Spec) |
| Max Oxygen Content | ≤ 0.20% | ≤ 0.13% |
| Tensile / Yield Strength | Slightly higher (~900–1000 MPa) | Slightly lower (~860–930 MPa) |
| Fracture Toughness (K_IC) | 55–75 MPa√m | 75–90 MPa√m (~30% higher) |
| Elongation / Ductility | ~10–14% | ~14–16% |
| Primary Advantage | High static strength, lower raw material cost | Superior fatigue resistance, higher crack tolerance |
