- Product Description
Grade 23 Titanium Rod – High-Purity Ti-6Al-4V ELI for Medical & Aerospace Applications
Baoji Jucheng Titanium Industry Co., Ltd., headquartered in China's Titanium Valley, delivers enterprise-grade grade 23 titanium rod manufactured to ASTM F136 and ASTM B348 standards. With over 20 years of titanium expertise and a 120,000-square-meter production base, we maintain approximately 3,000 tons of titanium inventory for rapid delivery. Our rod features Extra Low Interstitials (Oxygen ≤0.13%, Iron ≤0.25%), offering superior ductility and fracture toughness. Available in diameters Φ6–Φ450mm and lengths up to 12,000mm, our rods undergo vacuum melting, precision forging, and multi-stage inspection to meet critical requirements in medical implants and cryogenic aerospace components where catastrophic failure is non-negotiable.

Quality Assurance Process
Our multi-stage inspection protocol exceeds industry standards:
Chemical Analysis: Optical Emission Spectroscopy verifies ELI interstitial levels at five checkpoints during production.
Mechanical Testing: Every batch undergoes tensile and elongation testing per ASTM E8. Results are documented with full material traceability.
Microstructural Evaluation: Metallographic examination at 100-500x magnification ensures uniform Alpha-Beta phase distribution. We eliminate harmful alpha-case formations that compromise implant safety.
Non-Destructive Testing: Ultrasonic testing per AMS 2631 Class A detects internal voids. Eddy current testing identifies surface micro-cracks before shipment.
Our quality team holds 4 invention patents and 41 utility model patents. This drives continuous process improvements validated through industry-academic partnerships.

Applications Across Critical Industries
Our rods are used by medical device makers for joint prosthesis and spine implants. The low modulus preserves excellent strength while lowering the risk of bone resorption.
Our material is specified by aerospace experts for parts of cryogenic fuel systems. At high temperatures, catastrophic failures are avoided thanks to the enhanced fracture toughness.
Superior corrosion resistance in chloride conditions is advantageous for chemical processing facilities. Without sacrificing quality, our 3,000-ton inventory helps meet pressing project deadlines.
Applications in marine engineering take advantage of the alloy's resistance to corrosion in saltwater. For specialist subsea equipment, we provide custom lengths up to 12 meters.

Why Choose Our Grade 23 Titanium Rod?
Our grade 23 titanium rod stands out for its exceptional biocompatibility and damage tolerance. The ELI designation ensures reduced interstitial content, directly improving stress corrosion cracking resistance.
With a modulus of elasticity at 113.8 GPa—roughly half that of stainless steel—it closely matches human cortical bone. This minimizes stress shielding effects in orthopedic applications.
Our advanced production lines integrate rotary forging and centerless grinding. This guarantees h6-h9 dimensional tolerances essential for CNC machining in medical device manufacturing.
Annual production exceeds 500 sets of titanium equipment. Our technical team collaborates with Northwest Nonferrous Metals Research Institute and Tsinghua University to optimize alloy microstructures.
FAQ
Q: What distinguishes normal Grade 5 titanium from Grade 23 titanium?
A: Extra Low Interstitials with Oxygen ≤0.13% are seen in Grade 23, compared to 0.20% in Grade 5. For cryogenic applications and medical implants, this offers 15–20% greater ductility and higher fracture toughness.
Q: Can you offer material certificates for the production of medical devices?
A: Yes. ASTM F136 compliance certificates with complete chemical composition reports and mechanical property test data that may be linked to particular melt batches are included with every shipment.
Q: Which surface treatments are ideal for orthopaedic implants?
A: For articulating surfaces, we suggest polished or centerless ground treatments. Sandblasted coatings improve osseointegration for bone-integration components without sacrificing corrosion resistance.
Q: How can dimensional accuracy for tight-tolerance machining be guaranteed?
A: We obtain h6-h9 tolerances using our rotary forging technique in conjunction with precise centerless grinding. Dimensional displacement during subsequent CNC operations is prevented by post-annealing stress alleviation at 480–595°C.
Q: What is the average lead time for orders with custom lengths?
A: From our 3,000-ton inventory, standard diameters up to 6000mm ship in 7–10 days. Including specific heat treatment and inspection procedures, custom lengths up to 12,000mm take 15–20 days to complete.
