Detailed Description
The ASTM F136 6Al-4V ELI titanium bar is a titanium alloy bar conforming to the ASTM F136 standard, typically manufactured from Ti-6Al-4V ELI (Extra Low Interstitial) alloy. It exhibits exceptional mechanical properties and corrosion resistance, making it ideal for critical applications. Key features include:
Material Composition: Primarily composed of titanium, aluminum, and vanadium, offering high strength, low density, excellent corrosion resistance, and superior biocompatibility.
Specifications: Diameter ranges from 1.0 mm to 300 mm, with lengths up to 6000 mm. Custom lengths and surface treatments (e.g., polishing, pickling, satin finishing) are available.
Manufacturing Process: Includes forging, rolling, annealing, and heat treatment to ensure precise dimensional accuracy and optimal material performance.
Quality Assurance
NDT Testing: 100% ultrasonic testing (UT) and internal/external defect inspection.
Batch Traceability: Laser marking of heat numbers, alloy grades, and dimensions for full lifecycle tracking.

The primary distinction between Ti-6Al-4V ELI (Grade 23) and Ti-6Al-4V (Grade 5) is the reduced maximum oxygen content (0.13% in ELI), which enhances fracture toughness and biocompatibility. ASTM F136 6Al-4V ELI titanium bar is widely used in the medical industry, particularly for implants and surgical instruments, due to its biocompatibility, corrosion resistance, high strength, and toughness.
We supply titanium bars in various grades and dimensions for multiple industries, including:
Medical: Orthopedic and dental implants, medical devices.
Aerospace: Fasteners, profiles, forgings.
Industrial Applications.
The ultra-low interstitial (ELI) content ensures exceptional fracture toughness, making it ideal for load-bearing medical implants.

Functional Characteristics
High Strength & Light Weight: Density of ~4.51 g/cm³ (43% lighter than steel) with comparable strength.
Corrosion Resistance: Excellent resistance to acids, alkalis, salts, and seawater.
Biocompatibility: Ideal for medical implants and devices due to low reactivity and tissue compatibility.
Temperature Resistance: Suitable for use in extreme temperatures ranging from -273°C to 500°C.
Manufacturing Process
Billet Preparation: Selection of titanium or titanium alloy ingots meeting standard requirements.
Forging: Forging at 1000-1200°C for titanium alloys, with a deformation rate of 50-65%. Surface defects are removed post-forging.
Deformation Processing: Additional forging, grinding, and rolling at 1000-1150°C with controlled deformation rates.
Heat Treatment: Recrystallization annealing at 800-850°C to relieve stress and form equiaxed grain structures.
Finishing: Drawing, cutting, straightening, and polishing to achieve precise dimensions and surface quality.
Inspection: Verification of tolerances, surface finish, chemical composition, mechanical properties, and microstructure.
Packaging: Packaging of certified products for shipment.
