Ti-6Al-4V (Grade 5) Titanium Powder

Titanium Alloy Powders · Metal Additive Manufacturing Powder

Ti-6Al-4V (Grade 5) is the workhorse titanium alloy of metal additive manufacturing, accounting for the largest share of titanium AM parts in aerospace, medical implants and motorsport. It delivers a 4.43 g/cm³ density with ~1,000-1,050 MPa tensile strength — roughly 40% lighter than steel at comparable strength. LPBF as-built Ti64 typically reaches 1,040 MPa UTS and 965 MPa YS with 17% elongation; annealing improves ductility while hot isostatic pressing (HIP) restores fatigue performance for structural aerospace use. Because titanium is reactive, powder must be produced by inert gas atomization with tight oxygen control (Grade 5 allows O ≤0.20%; Grade 23 ELI requires ≤0.13%). Spherical, low-oxygen powder with 15-45 µm or 15-53 µm cuts is standard for LPBF. When comparing titanium powder suppliers, oxygen content, flowability and traceability (sponge source, lot certificates per ASTM F2924) are the three factors that separate professional lots from commodity ones.
