Titanium Grade 23 (Ti-6Al-4V ELI, UNS R56401) is the extra-low-interstitial variant of Grade 5 with oxygen ≤ 0.13%. Higher fracture toughness and cryogenic toughness make it the international standard for orthopaedic and dental implants (ASTM F136 / ISO 5832-3).
As a manufacturer and global exporter of special alloys since 2012, Shanghai Hangbo Alloy Group Co., Ltd. supplies Titanium Grade 23 (Ti-6Al-4V ELI) as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), seamless tubes & pipes (φ6–630 mm OD, 0.5–40 mm wall), forgings & rolled rings (up to 7500 kg, 3500 mm OD), machined parts to your drawings — all with EN 10204 3.1 certified material test reports.

Frequently asked questions
How does implant-grade TC4 ELI differ from standard TC4?
TC4 ELI (Grade 23) limits oxygen to 0.13% and iron to 0.25%, while standard TC4 (Grade 5) allows oxygen to 0.20%. Lower interstitial content yields higher fracture toughness and better cryogenic and fatigue performance — essential for implants under long-term cyclic load — and requires a fully traceable certificate to ASTM F136.
What forms and sizes are available?
We supply Titanium Grade 23 (Ti-6Al-4V ELI) as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), seamless tubes & pipes (φ6–630 mm OD, 0.5–40 mm wall), forgings & rolled rings (up to 7500 kg, 3500 mm OD), machined parts to your drawings. Custom lengths, tolerances and machining to drawing are available on request.
What is the MOQ and lead time?
MOQ is flexible — trial orders from a single piece are welcome. Stock sizes ship in 3–7 days; custom forgings and machined parts typically 15–35 days depending on quantity and process.
Can you provide third-party inspection and shipping to my port?
Yes. SGS / BV / TUV or your nominated inspector can witness all tests before shipment. Full export documentation is provided, and we ship worldwide by sea or air on FOB, CIF or DDP terms.
