ASTM F136 Ti6Al4V ELI For Surgical Implant

ASTM F136 Ti6Al4V ELI For Surgical Implant

For vital biomedical applications, LINHUI Titanium provides ASTM F136 Ti6Al4V ELI For Surgical Implant certified materials with regulated interstitial elements (Iron <0.25%, Oxygen <0.13%), guaranteeing exceptional ductility and fracture toughness. With full heat traceability, our Ti6Al4V ELI grade satisfies the strict standards of EN 10204 3.1 certification.

We provide a variety of configurations: Bar (Dia. 4.76–101.6mm), Strip (Dia. ≤4.76mm × Width ≤610mm), Sheet (Dia. ≤4.76mm × Width ≥610mm), Plate (Dia. 4.76–101.6mm × Width ≥254mm), and Wire (Dia. ≤4.76mm). To get rid of flaws, every batch is subjected to 100% NDT inspection, which includes eddy current and ultrasonic testing. Your implant manufacture stays on schedule with stock supply in 3–7 days and thickness tolerance managed within ±0.05mm.

Key Features & Benefits

Excellence in Biocompatibility

By lowering interstitial contaminants, the ELI designation avoids cytotoxicity and allergic responses. Your implants easily meet ISO 5832-3 and FDA compliance requirements.

Improved Mechanical Efficiency

Brittle fracture upon surgical insertion is prevented by a minimum tensile strength of 860 MPa with >10% elongation. In joint replacements, the low modulus (113 GPa) reduces stress-shielding by matching cortical bone.

Resistance to Corrosion

For many years, the stable TiO₂ passive coating prevents corrosion from bodily fluids. Ion leaching and pitting corrosion are eliminated as causes of implant failure.

MRI Security

Minimal picture artifacts are produced by non-ferromagnetic characteristics. After surgery, your patients have safe MRI scans without having their devices taken out.

Manufacturing Process

VAR, or vacuum arc remelting

Triple-melted ingots provide a uniform microstructure and do away with macro-segregation. Every batch has the same mechanical qualities.

Regulated Hot Rolling

Grain structure is refined at forging temperatures between 900 and 950°C, increasing fatigue resistance. Under cyclic stress, our alpha-beta balance stops cracks from spreading.

Accurate Cold Rolling

During your machining processes, stable formation is ensured by maintaining a thickness tolerance of ±0.05mm. After pickling, the surface polish satisfies Ra ≤1.6 μm.

Verification of Heat Treatment

Remaining tensions are stabilized by annealing at 730°C. Equiaxed alpha grains necessary for surgical-grade certification are confirmed by microstructure examination.

Quality Inspection

100% Ultrasonic Testing

Every bar and plate undergoes UT per ASTM E2375 to detect internal voids exceeding 0.8mm diameter.

Eddy Current Scanning

All wire and strip products pass EC inspection per ASTM E571, ensuring zero surface defects.

Tensile & Impact Testing

Sample testing at 10% frequency verifies yield strength and elongation. Charpy impact values exceed 27 J at room temperature.

Chemical Analysis

ICP-OES and combustion analysis confirm interstitial element compliance. Each heat lot receives a certified mill test certificate (EN 10204 3.1).

Applications Of ASTM F136 Ti6Al4V ELI For Surgical Implant

Implants for Orthopedics

The high-cycle fatigue resistance of this material is essential for hip balls, acetabular cups, and femoral stems. Periprosthetic osteolysis is prevented by the biocompatible surface.

Devices for Spinal Fixation

ELI ductility is advantageous for rods, interbody cages, and pedicle screws. Intraoperatively, surgeons shape spinal rods without creating microcracks.

Abutments and Dental Implants

The bacterial-rich oral environment fosters the growth of the corrosion-resistant TiO₂ layer. In clinical trials, osseointegration rates are higher than 95%.

Hardware for Trauma Repair

Intramedullary nails, screws, and plates all take advantage of the material's strength-to-weight ratio. Soft tissue irritation is reduced by a smaller implant profile.

FAQ

Q: What distinguishes ASTM B348 Grade 23 from ASTM F136?

A: B348 is used in general industrial applications, whereas F136 enforces more stringent microstructure controls and defect restrictions specifically for surgical implants.

Q: Does this substance pass safety tests for MRIs?

A: Yes. It is safe for patients who need post-operative imaging since it is non-ferromagnetic and causes little artifacts.

Q: Why is "ELI" important when it comes to surgical screws?

A: During high-torque insertion, a lower oxygen level increases ductility by 30%, reducing screw-head fractures.

Q: After machining, is passivation necessary?

A: To eliminate free iron contamination and improve the protective oxide layer, we advise using ASTM F86 passivation.

Q: Are you able to provide materials for implants that are 3D printed?

A: Wrought shapes are subject to ASTM F136. We also provide ASTM F3001 powder upon request, which is necessary for additive manufacturing.---
