Grade 5 vs Grade 23 FAQ

Grade 5 is the standard Ti-6Al-4V alloy, while Grade 23 (also called Ti6Al4V ELI) is the extra-low interstitial version. Grade 23 offers better fracture toughness and is more suitable for medical implants.

Yes, Grade 23 titanium is preferred for implants because it meets ASTM F136 bar stock standards and provides improved biocompatibility and fatigue resistance compared to Grade 5.

Grade 23 machinability is typically better due to its lower interstitial content. This can lower tool wear and improve part accuracy for precision Ti-6Al-4V forging in China or local U.S. manufacturing.

Grade 23 titanium price is generally higher than Grade 5 due to tighter control and extra processing needed for ELI titanium wire and plates like AMS 4928 plate.

For many applications, yes. But for critical medical uses, especially titanium implant material, Grade 23 is recommended to ensure safety and compliance.

Grade 5 often fits better for aerospace parts and structural uses, while Grade 23 shines in medical and high-reliability components due to ELI properties.
