Grade 23 Titanium

Grade 23 (Ti-6Al-4V ELI) is an extra-low-interstitial version of Grade 5 titanium, with tighter limits on elements such as oxygen, nitrogen, and carbon. This provides improved fracture toughness, ductility, and fatigue performance, making it widely used for medical implants and high-reliability aerospace components.

Appearance & Properties

Color: Silver-gray to silvery white

Density: Approx. 4.43 g/cm³

Tensile Strength: Typically around 860 MPa or higher, depending on specification and condition

Corrosion Resistance: Excellent

Machinability: Difficult

Strength-to-Weight Ratio: Excellent

Biocompatibility: Excellent

Fatigue Resistance: Excellent

Magnetism: Essentially non-magnetic

Surface Finishes: Blasting, polishing, anodizing, passivation, PVD coating, etc.

Typical Applications

Grade 23 Titanium is widely used in medical devices, orthopedic implants, dental applications, aerospace, and high-reliability precision equipment.

Typical parts include orthopedic implants, bone plates, bone screws, dental implant components, medical-device parts, aerospace structures, and high-reliability precision CNC components.

Advantages

• Excellent strength-to-weight ratio

• Good fracture toughness and fatigue performance

• Excellent corrosion resistance

• Good biocompatibility

• Particularly suitable for medical implants and high-reliability applications

Limitations

• Difficult to CNC machine

• Generally more expensive than standard Grade 5

• Low thermal conductivity increases thermal load on cutting tools

• Medical implant applications require compliance with applicable material, manufacturing, and quality-system requirements
