Composition and Mechanical Properties of G23 Titanium
G23 titanium is a specific grade of titanium alloy that is particularly valued in medical and high-performance applications. The alloy belongs to the titanium Grade 23 family, also known as Ti-6Al-4V ELI (Extra Low Interstitial), which is a refined version of the commonly used Grade 5 titanium alloy. The primary difference lies in its enhanced purity and reduced interstitial elements such as oxygen, nitrogen, and iron, which significantly improve its mechanical properties and biocompatibility.
The typical chemical composition of G23 titanium includes:
- Titanium (Ti): Balance
- Aluminum (Al): Approximately 6%
- Vanadium (V): Approximately 4%
- Oxygen (O): Max 0.13%
- Iron (Fe): Max 0.25%
- Carbon (C): Max 0.08%
- Nitrogen (N): Max 0.05%
- Hydrogen (H): Max 0.0125%
This composition ensures that G23 titanium exhibits superior strength-to-weight ratio, corrosion resistance, and excellent fatigue properties, making it ideal for applications such as surgical implants, aerospace components, and high-stress mechanical parts.
Mechanical Properties
G23 titanium has mechanical properties that make it suitable for demanding environments, especially where biocompatibility and durability are critical. Below is a summary of its key mechanical properties:
| Property | Typical Value | Unit |
|---|---|---|
| Ultimate Tensile Strength (UTS) | 900 – 950 | MPa |
| Yield Strength (0.2% offset) | 830 – 880 | MPa |
| Elongation at Break | 10 – 15 | % |
| Modulus of Elasticity | 113.8 | GPa |
| Hardness (Rockwell C) | 36 – 40 | HRC |
| Density | 4.43 | g/cm³ |
These mechanical properties highlight the alloy’s strength and flexibility, which are critical for reducing implant failure rates and maintaining structural integrity under cyclic loading conditions. The lower oxygen content in G23 compared to standard Grade 5 titanium enhances its fracture toughness and fatigue resistance, making it a preferred material in long-term implant applications.
Applications of G23 Titanium
G23 titanium’s unique combination of strength, corrosion resistance, and biocompatibility enables its widespread use in several advanced fields:
- Medical implants: Due to its excellent biocompatibility and resistance to body fluids, G23 is commonly used in orthopedic implants, dental implants, bone screws, and cardiovascular devices. The reduced interstitials minimize allergic reactions and improve osseointegration.
- Aerospace components: The high strength-to-weight ratio and fatigue resistance make it suitable for critical aerospace parts, including airframes, turbine engines, and fasteners.
- Sports equipment: High-performance sporting goods such as bicycle frames, golf clubs, and tennis rackets benefit from the alloy’s lightweight and strength.
- Chemical processing: Its corrosion resistance in aggressive environments allows for applications in chemical plants and marine hardware.
- Precision engineering: Used in components requiring tight tolerances and high reliability, such as surgical instruments and high-end mechanical assemblies.
