Grade 5 Titanium (Ti-6Al-4V)
Grade 5 — Ti-6Al-4V, TC4 in China, 6Al-4V by name everywhere. UNS R56400. 895 MPa minimum tensile with corrosion resistance close to CP grades, and the machining behaviour engineers actually design around. The alloy we quote most after Gr2.

Forms & Size Ranges
Bar φ3–350 (we routinely answer φ16–φ145 enquiries) · plate · rings & discs · machined to drawing · bolts.
Annealed vs STA
Annealed Gr5 machines friendlier and forms a little; solution-treated + aged (STA) gives the highest usable strength for thin, loaded sections. State the condition on the purchase spec or let our quotation propose it.
Aerospace & Medical Context
AMS 4928 and ASTM F136/GB/T 13810 names appear on many Gr5/Gr23 enquiries. We can quote material against those published specs; we are not AS9100/NADCAP-certified and do not claim aerospace or implant qualification — we supply the metal and machining; certification stays with the buying programme.
Price Logic (qualitative)
Gr5 costs more per kg than Gr2 — alloying, forging routes and scrap handling — but design strength often makes the part cheaper through smaller sections. Send the drawing; we compare both grades on the same line if useful.
