ASTM F136 Ti-6Al-4V ELI (Grade 23) titanium bar is wrought alpha-beta titanium alloy bar for the manufacture of surgical implants, UNS R56401. ELI means extra-low interstitial. Lower limits on oxygen, iron and other interstitial elements than conventional Ti-6Al-4V improve fracture toughness, fatigue-crack-growth resistance and low-temperature toughness while retaining high specific strength, corrosion resistance and biocompatibility.<\/p>

The alloy is widely used as precision machining stock for orthopedic, trauma, spinal, dental and other implantable devices. ASTM F136 specifies medical-alloy raw material; the finished implant still requires device-level validation for actual diameter, microstructure, surface integrity, fatigue, cleaning and sterilization, biological evaluation and applicable regulation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Main Characteristics<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
  • Medical Ti-6Al-4V ELI:<\/strong> Lower maximum levels of oxygen, iron, carbon, nitrogen and hydrogen improve damage tolerance while preserving the high strength of Ti-6Al-4V, making the alloy suitable for implant devices sensitive to fatigue and fracture performance.<\/li>
  • Controlled alpha-beta chemistry:<\/strong> Aluminum stabilizes alpha and vanadium stabilizes beta. Al, V and interstitial elements require heat-specific control for consistent strength, ductility, microstructure and processing response.<\/li>
  • Good biocompatibility:<\/strong> A stable TiO2 passive film and extensive clinical use support its role as a common implant material. The finished device still requires biological evaluation under applicable regulations and standards such as ISO 10993.<\/li>
  • Good corrosion resistance:<\/strong> Performance is generally excellent in saline, body fluids and many chloride environments, but fretting, crevices, dissimilar-metal coupling, fluoride media and surface contamination require device-level evaluation.<\/li>
  • Weldable with strict shielding:<\/strong> Qualified GTAW\/TIG, laser, electron-beam or resistance welding may be used. The pool, root and hot heat-affected zone must be fully protected from O, N, H and C contamination.<\/li>
  • High strength with limited cold formability:<\/strong> Room-temperature strength is substantially above unalloyed titanium, but cold-forming margin is limited and springback is significant. Complex forming normally uses warm or hot forming, staged deformation and, when needed, intermediate annealing with device-level validation.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Aluminum and vanadium:<\/strong> Al is 5.5-6.5% and V is 3.5-4.5%, together producing a heat-treatable alpha-beta microstructure. Chemical homogeneity, melting and thermomechanical processing affect microstructure and final properties.<\/li>
    • Oxygen, iron and interstitials:<\/strong> The ELI grade uses lower O, Fe, C, N and H limits to improve toughness and fatigue-crack-growth behavior. Excess levels may increase hardness, reduce ductility or create hydrogen-embrittlement risk.<\/li>
    • Residual elements:<\/strong> Each and total limits must be controlled. The material report must correspond to the heat; testing only Al and V does not satisfy the complete chemistry requirement.<\/li>
    • Titanium content:<\/strong> The specification states Titanium: Balance. A nominal grade or medical-grade claim does not replace heat-specific analysis, the material report and contract testing.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
