Performance and application of Gr5ELI high-precision medical Gr23 titanium rod
Oct 23, 2025
The requirements for implant materials can be divided into three aspects: biocompatibility between the material and the human body, corrosion resistance of the material in the human body environment, and mechanical properties of the material.
As a long-term implant material, there are seven specific requirements:
1. Corrosion resistance
2. Biocompatibility
3. Excellent mechanical and fatigue properties
4. Toughness
5. Low elastic modulus
6. Good wear resistance in the assembly
7. Satisfactory price.








1. Industrially pure titanium
2. Ti-6Al-4V and Ti-6Al-4VELi alloys
3. Ti-6Al-7Nb alloy
4. New -type alloys
5. Ti-Ni alloys
Gr23 Titanium Rod Specifications: φ4-120mm
Tolerance: 0.03mm
Chemical Composition of GR23: N <= 0.03, C <= 0.08, H <= 0.0125, Fe <= 0.25, O <= 0.13, 5.5 <= Al <= 6.5, 3.5 <= V <= 4.5
Titanium and titanium alloys are widely used in clinical applications to manufacture artificial joints, bone plates, and screws for bone and joint injuries caused by trauma or tumors. They are also used in hip joints (including the femoral head), knee joints, elbow joints, metacarpophalangeal joints, interphalangeal joints, mandibles, artificial vertebrae (spinal orthoses), pacemaker housings, artificial hearts (heart valves), dental implants, titanium-nickel orthodontic appliances, and titanium mesh for skull reshaping.
