Ti6Al7Nb Titanium Alloy Bar
LINHUI TITANIUM specializes in producing precision Ti6Al7Nb Titanium Alloy Bar that meets ASTM F1295 and ISO 5832-11 medical-grade standards. Our advanced forging capabilities deliver rings with OD ≤ 1300mm and Height ≤ 250mm, and discs with OD ≤ 1100mm and Height ≤ 40mm. This vanadium-free alloy offers Tensile Strength exceeding 900 MPa and Yield Strength greater than 800 MPa, with elongation >10%.
The substitution of niobium eliminates cytotoxicity concerns while maintaining superior mechanical performance. With 200+ tons of inventory and ISO 9001:2015 certification, we ensure rapid delivery within 3–7 days for stock orders. Each product includes full traceability documentation per EN 10204 3.1/3.2.
Key Features & Benefits
Our bars feature a stable TiO2/Nb2O5 passivation layer that prevents ion release in physiological environments. The reduced elastic modulus (closer to cortical bone) minimizes stress shielding in orthopedic implants.
Niobium content (6.5-7.5%) provides exceptional biocompatibility for permanent implants. Fine equiaxed alpha-beta microstructure ensures consistent fatigue resistance under cyclic loading.
Centerless ground and peeled finishes achieve h7/h6 tolerances required for precision CNC machining.

Manufacturing Process
We utilize vacuum bend remelting (VAR) for homogeneous ingot structure. Multi-stage hot fashioning refines grain measure to ETTC-2 standard.
Solution treatment at 900–950°C taken after by controlled cooling optimizes the alpha-beta stage adjust. Centerless pounding evacuates alpha-case and accomplishes tight distance across tolerances.
All bars experience push alleviation toughening to kill leftover stresses from machining.
Quality Inspection
100% Ultrasonic Testing (UT) per AMS 2631 Course A1 identifies subsurface absconds. Spectroscopic examination confirms chemical composition compliance with ISO 5832-11 limits.
Microstructural assessment affirms fine equiaxed grain structure free from ceaseless alpha systems. Mechanical testing incorporates pliable, abdicate, and stretching confirmation per batch.
Third-party review accessible through SGS, TÜV, and DNV for basic applications.
Applications
Orthopedic Inserts: Femoral stems, hip prostheses, and knee joint components handle millions of stack cycles in destructive synovial liquid environments.
Dental Frameworks: Projections and prosthetic screws advantage from predominant osseointegration and resistance to rumination forces.
Spinal Obsession: Pedicle screws and interfacing bars give intra-operative forming capability while maintaining flexibility during combined surgery.

FAQ
Q: How does this combination compare to Ti6Al4V ELI?
A: Niobium replaces vanadium, killing harmfulness concerns for long-term inserts and patients with metal sensitivities.
Q: Is machining difficult?
A: Comparable to Review 5 titanium. Requires unbending tooling and high-pressure coolant, but optimized CNC parameters guarantee proficient processing.
Q: What surface wraps up are available?
A: Centerless ground or peeled wraps up with h7/h6 resistances expel alpha-case for coordinate machining.
Q: Does it meet FDA requirements?
A: Yes, complies with ASTM F1295 and ISO 5832-11, giving vital documentation for 510(k) clearance.
Q: Can it be anodized?
A: Great anodizing properties for Sort II color coding or Sort III difficult coating on strung components.
