Provide High Quality Grade 23 Titanium Pipe to Customers Around The World
Grade 23 titanium tubing, also known as Ti-6Al-4V ELI, is a high-strength, lightweight alloy composed of titanium with 6% aluminum and 4% vanadium in an extra-low interstitial (ELI) form.It is an improved alloy based on the classic Ti-6Al-4V (grade 5) by further reducing the content of interstitial elements such as oxygen, iron, and nitrogen (such as oxygen content ≤ 0.13%).Its extra-low interstitial (ELI) composition significantly enhances fracture toughness and fatigue resistance compared to standard titanium alloys, allowing it to perform reliably under cyclic loading conditions. The alloy maintains its impressive strength-to-weight ratio even at cryogenic temperatures, unlike many metals that become brittle in extreme cold. Additionally, Grade 23 exhibits superior corrosion resistance in both acidic and chloride environments, outperforming many stainless steels and other titanium grades in aggressive chemical settings.
Where is Grade 23 titanium pipe used?
Grade 23 titanium tubing has unique applications in cutting-edge medical devices, particularly orthopedic implants such as spinal fusion cages and joint replacement components, which require lifelong biocompatibility and fatigue resistance. It is particularly well-suited for dental implant systems, where osseointegration (a direct structural connection between bone and implant) is crucial to the long-term success of the system. In aerospace, it is the material of choice for hydraulic and fuel lines in commercial and military aircraft, which must balance weight reduction with extreme pressure requirements. The material’s properties also make it an ideal choice for high-performance bicycle frames used by professional cyclists, where its vibration-absorbing properties and fatigue resistance provide a competitive advantage.
Key Notes:
ELI (Extra Low Interstitial): Grade 23 has stricter limits on oxygen, nitrogen, hydrogen, and carbon compared to standard Grade 5 (Ti-6Al-4V) to enhance ductility and biocompatibility.
Primary alloying elements: Aluminum (Al) and vanadium (V) contribute to strength and phase stability.
Impurity control: Low iron, carbon, nitrogen, and hydrogen ensure superior corrosion resistance and fatigue performance.
Key performance:
High strength + high toughness: tensile strength can reach 895-930 MPa (annealed state), elongation ≥10%, better than ordinary Grade 5, suitable for scenes with dynamic loads.
Excellent corrosion resistance: acid resistance (such as hydrochloric acid, sulfuric acid), alkali resistance, seawater resistance, outstanding performance in medical implants and chemical equipment.
Biocompatibility: non-magnetic, non-toxic, excellent compatibility with human tissue, is the preferred material for orthopedic implants.
Processability: can be formed by forging, rolling, machining, welding performance is better than ordinary titanium alloy.

Grade 23 titanium tube form (4)
-
Titanium seamless tubes are made by piercing and drawing solid titanium bars, and the hollow part of the tube is made by piercing or hot extrusion. Titanium seamless tubes are ideal for very large diameter to wall thickness ratios and have very good external dimensional tolerances.
-
Titanium welded pipe is a tubular product made of strip titanium that is roll formed and fusion welded along the longitudinal seam. The welding process used by Daxun Alloy does not use any filler metal during the welding process.
-
Titanium square tubes are drawn from round tubes or round tube billets and can be formed into right angles or rounded corners. They can also be cold extruded, which is efficient and low cost. The only disadvantage is that the tolerance will gradually increase.
-
Tubular products are welded and then re-drawn to final size. Welding and drawing is ideal for producing thick walled, large diameter tubes that cannot be welded directly to size but still offer cost savings over seamless tubes. All Daxun welded and drawn tubes are bright annealed.
Recent hot case projects and products
Grade 23 titanium pipe (Ti-6Al-4V ELI) is an extra low interstitial version of the popular Grade 5 titanium alloy. It contains reduced levels of oxygen, iron, and other interstitial elements, which results in improved fracture toughness, better fatigue resistance, and enhanced biocompatibility while maintaining high strength-to-weight ratio.
Grade 23 titanium tubes offer excellent biocompatibility, reducing the risk of adverse reactions when implanted in the human body. They have a modulus of elasticity closer to bone than many other metals, which helps reduce stress shielding. Additionally, their superior fatigue resistance ensures long-term performance in load-bearing medical applications.
Grade 23 titanium tubes exhibit outstanding corrosion resistance in most environments, including seawater, chlorides, and acidic conditions. The protective oxide layer that forms on the surface provides exceptional resistance to pitting and crevice corrosion, making them suitable for marine and chemical processing applications.
