Gr5 vs Gr23 Titanium Alloy Bar
Jan 15, 2026
What is GR5 titanium?
Titanium Grade 5, also known as Ti-6Al-4V, is the most commonly used titanium alloy. It is composed of approximately 90% titanium, 6% aluminum, and 4% vanadium. This combination of elements gives Grade 5 titanium bars an excellent balance of strength, lightness, and corrosion resistance. It is often referred to as the "workhorse" of titanium alloys due to its versatility and widespread use in various industries, including aerospace, medical, automotive, and marine.
Key Properties of Grade 5 Titanium Bars:
High Strength: Ideal for demanding structural applications.
Lightweight: Lighter than many other metals, perfect for aerospace use.
Corrosion Resistance: Excellent in saltwater, acidic, and high-temperature environments.
Versatility: Widely used due to ease of fabrication and mechanical strength.

What is Titanium Grade 23?
Titanium Grade 23, or Ti-6Al-4V ELI (Extra Low Interstitials), is a modified version of Grade 5. The primary difference is the reduced content of interstitial elements such as oxygen and iron. These lower levels enhance its ductility and fracture toughness, making it ideal for high-performance applications in the medical and aerospace industries.
Key Properties of Grade 23 Titanium Bars:
Superior Biocompatibility: Preferred for medical implants like hip and dental replacements.
Higher Toughness and Ductility: More resistant to cracking under stress.
Corrosion Resistance: Exceptional in medical and marine environments.
Fatigue Resistance: Excellent for applications requiring precision and longevity.
Key Differences Between Grade 5 and Grade 23 Titanium Bars
| Property | Grade 5 Titanium (Ti-6Al-4V) | Grade 23 Titanium (Ti-6Al-4V ELI) |
|---|---|---|
| Composition | 90% Ti, 6% Al, 4% V | Same as Grade 5, but lower O & Fe |
| Strength | High tensile strength | Similar strength, improved toughness |
| Ductility & Toughness | Moderate | Superior |
| Corrosion Resistance | Excellent | Excellent, especially for medical use |
| Applications | Aerospace, marine, industrial | Medical implants, aerospace components |
| Cost | More affordable | Higher due to extra processing |
When to Use Grade 5 Titanium Bars?
Choose Grade 5 titanium bars for applications where high strength, lightweight, and corrosion resistance are crucial. Ideal for:
Aerospace structures
Automotive parts
Marine hardware
Industrial machinery
When to Use Grade 23 Titanium Bars?
Choose Grade 23 titanium bars for:
Medical implants (hip, dental, orthopedic)
Aerospace components requiring precision
High-performance parts needing ductility and toughness
Conclusion
Both Grade 5 and Grade 23 titanium round bars offer outstanding properties, but are tailored for different needs. Grade 5 is a reliable all-rounder, while Grade 23 excels in applications demanding extra toughness and biocompatibility.
