| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Beta annealed (~1020–1050 °C, slow cool + 730 °C stabilize) | Coarse lamellar structure for maximum fracture toughness and damage tolerance / creep resistance, at the cost of tensile strength and ductility. | 860 | 940 | 9 | 31 HRC | — |
Hot isostatic pressed | Default for fatigue- or fracture-critical aerospace/medical parts: closes gas porosity and lack-of-fusion, maximizing ductility and fatigue life. | 890 | 985 | 16 | 32 HRC | — |
As-deposited DED / LMD / wire-arc | Choose for large near-net shapes and repair cladding; coarser columnar prior-β grains give slightly lower strength and more anisotropy. | 910 | 1,010 | 11 | 34 HRC | 1 % IACS |
As-built EBM / EB-PBF | Self-annealed lamellar α+β from the hot build chamber — lower residual stress and near-wrought properties without further heat treatment. | 930 | 1,020 | 14 | 33 HRC | 1 % IACS |

SR-LPBFDefault LPBF + stress relief | Standard as-shipped condition for LPBF Ti64 parts: residual stress removed, α' partly decomposed, strength well above wrought Grade 5. | 1,020 | 1,120 | 12 | 35 HRC | — |

Working with Ti-6Al-4V (Grade 5) AM Powder-ANN
Is Ti-6Al-4V (Grade 5) AM Powder easy to machine?
Machine printed Ti64 at low surface speed (30–60 m/min carbide), heavy rigid setups, high-pressure flood coolant and sharp positive tooling; avoid dwelling to prevent work hardening and fire risk from fine chips.
Can Ti-6Al-4V (Grade 5) AM Powder be welded?
Readily fusion welded (GTAW/EBW/LBW) with full argon or vacuum shielding and trailing gas; keep interstitials low and post-weld stress relieve — no filler-free welding in open air.
Can Ti-6Al-4V (Grade 5) AM Powder be formed, bent or molded?
Formed only as a printed near-net shape; cold forming of printed stock is limited, use hot forming/superplastic forming above ~750 °C in inert atmosphere and design supports plus 650–800 °C stress relief on the plate before removal.
What surface finishes work on Ti-6Al-4V (Grade 5) AM Powder?
Blast, chemically mill or tumble to remove partially sintered powder, then machine or polish critical surfaces; Type II/III anodize (AMS 2488), passivate or plasma-spray HA for implants — never plate with hydrogen-charging processes.

Not especially — machinability is rated poor (22/100, worse than 55% of titanium grades). Machine printed Ti64 at low surface speed (30–60 m/min carbide), heavy rigid setups, high-pressure flood coolant and sharp positive tooling; avoid dwelling to prevent work hardening and fire risk from fine chips.
Can Ti-6Al-4V (Grade 5) AM Powder-ANN be welded?
Yes — weldability is rated good (65/100). Readily fusion welded (GTAW/EBW/LBW) with full argon or vacuum shielding and trailing gas; keep interstitials low and post-weld stress relieve — no filler-free welding in open air.
What surface finishes work on Ti-6Al-4V (Grade 5) AM Powder-ANN?
Blast, chemically mill or tumble to remove partially sintered powder, then machine or polish critical surfaces; Type II/III anodize (AMS 2488), passivate or plasma-spray HA for implants — never plate with hydrogen-charging processes.
Can Ti-6Al-4V (Grade 5) AM Powder-ANN be formed, bent or molded?
Formed only as a printed near-net shape; cold forming of printed stock is limited, use hot forming/superplastic forming above ~750 °C in inert atmosphere and design supports plus 650–800 °C stress relief on the plate before removal.
What is the maximum service temperature of Ti-6Al-4V (Grade 5) AM Powder-ANN?
Ti-6Al-4V (Grade 5) AM Powder-ANN is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
