Ti-6Al-4V ELI (Grade 23)

Ti-6Al-4V ELI (Extra Low Interstitial) is an extra-pure variant of the industry-standard Ti-6Al-4V titanium alloy, with tightly controlled oxygen and other interstitial elements to maximize ductility and fracture toughness. This material is the preferred choice in biomedical implants, aerospace components, and other applications where reliability and tissue compatibility are critical, as the reduced interstitial content enhances both mechanical reliability and biocompatibility compared to standard Ti-6Al-4V. Engineers select Grade 23 ELI when implant longevity, crack resistance, and minimal inflammatory response are non-negotiable—making it the de facto standard for orthopedic and cardiovascular devices despite higher material cost.
