Side-by-side chemical composition and mechanical property comparison.
Overview
Ti-10V-2Fe-3Al (Ti-10-2-3)
R56410
Near-beta titanium alloy developed for high-strength airframe forgings. UNS R56410. Solution treated + aged: Rm ~1195–1241 MPa, Rp0.2 ~1100–1120 MPa, A ~10%. Density 4.65 g/cm³, E-Modul 110 GPa. Best hot-die forgeability of any commercial titanium alloy. Deep-hardenable. AMS 4983/4984/4986/4987. Applications: aircraft landing gear (Boeing 777, Airbus A380), actuation components, helicopter rotor hubs, high-strength structural forgings.
Ti-6Al-4V ELI (Grade 23)
R56401
Extra Low Interstitial version of Ti-6Al-4V (Grade 5) — the gold standard for surgical implants. Reduced O (≤0.13%), Fe (≤0.25%), and C (≤0.08%) versus Grade 5 enhance ductility, fracture toughness, and fatigue strength with some strength reduction. Biocompatible (ASTM F136), MRI-compatible, and spontaneously passivating. Used for orthopedic implants (hip/knee replacements, spinal fixation), dental implants, bone plates/screws, aerospace structural components requiring high damage tolerance, and cryogenic vessels down to -320°C. W.Nr. 3.7165.
