Products Description
Gr5(Ti-6Al-4V) and Gr23(Ti-6Al-4V ELI) are two titanium alloys widely used in the medical field, with excellent strength-to-weight ratio, corrosion resistance and biocompatibility. Gr5 titanium alloy rods are mainly used for high-load medical devices and implants, while Gr23 is particularly suitable for long-term medical devices implanted in the human body due to its ultra-low impurity content and high biocompatibility.
chemical composition
- Gr5 Titanium Alloy:
-Titanium (Ti): about 90%
-Aluminum (Al):6%
-Vanadium (V):4%
- Gr23 Titanium Alloy:
-Titanium (Ti): about 90%
-Aluminum (Al):6%
-Vanadium (V):4%
-Oxygen (O):≤ 0.13%(lower oxygen content compared to Gr5)
physical properties
-Density: 4.43 g/cm & sup3;
-Melting point: 1660°C
-Tensile strength:
- Gr5:≥ 895 MPa
- Gr23:≥ 860 MPa
mechanical properties
Yield Strength:
- Gr5:≥ 830 MPa
- Gr23:≥ 795 MPa
-ductility: good, suitable for forming and welding
-Fatigue performance: high, able to withstand long mechanical loads
Application areas
-Orthopaedic Implants: Gr5 and Gr23 titanium alloy rods are used in the manufacture of bone nails, intramedullary nails, bone plates and artificial joints.
-Dental implants: Due to its corrosion resistance and biocompatibility, it is widely used in dental implants.
-Surgical instruments: Suitable for surgical instruments, such as jigs and bone plates, due to their high strength and antibacterial properties.
