Ti 6Al 4V (Grade 5)

Ti-6Al-4V (Grade 5) — Engineering & Procurement Topic Overview (19 Articles)

Ti-6Al-4V (ASTM Grade 5, UNS R56400, Werkstoffnr. 3.7165, GB/T TC4) is the workhorse alpha-beta titanium alloy, accounting for more than 50% of global titanium usage. Combining a minimum tensile strength of 895 MPa and yield strength of 828 MPa with a density of just 4.43 g/cm³, Ti-6Al-4V delivers an exceptional specific strength-to-weight ratio up to 350–400°C alongside full seawater corrosion immunity.

We supply Ti-6Al-4V across rolled sheets and creep-flattened plates (ASTM B265 / AMS 4911), precision ground bars and billets (ASTM B348 / AMS 4928), open-die and ring forgings (ASTM B381), and 5-axis CNC machined parts. The articles below explore Grade 5 forging routes, machining parameters, and supply-chain lead times.
