Working with Ti-6Al-4V ELI (Grade 23) AM Powder POWDER
Is Ti-6Al-4V ELI (Grade 23) AM Powder easy to machine?
Low thermal conductivity and chemical reactivity: use rigid setups, sharp uncoated-carbide or AlTiN tools, 30–60 m/min, heavy flood coolant, and never dwell in the cut.
Can Ti-6Al-4V ELI (Grade 23) AM Powder be welded?
Excellent by GTAW, laser and EBW under high-purity argon or vacuum with full back-purge; keep O/N/H pickup low and avoid porosity from residual powder or contamination.
Can Ti-6Al-4V ELI (Grade 23) AM Powder be formed, bent or molded?
Processed by L-PBF/EB-PBF/DED rather than forming; keep powder dry and O₂ controlled, orient parts to limit overhangs, stress relieve before removal from plate, and HIP for fatigue-rated parts.
What surface finishes work on Ti-6Al-4V ELI (Grade 23) AM Powder?
Support removal plus machining, abrasive/chemical polishing or electropolishing; anodize per AMS 2488 for color/bio-surfaces, or grit-blast/plasma-spray HA on implants.

Ti-6Al-4V ELI (Grade 23) AM Powder POWDER has a typical yield strength of 1,010 MPa (146 ksi) and a tensile strength of 1,100 MPa (160 ksi) — stronger than 93% of titanium grades. Strength varies by condition: see the 10 listed tempers.
Is Ti-6Al-4V ELI (Grade 23) AM Powder POWDER easy to machine?
Not especially — machinability is rated not recommended (0/100, worse than 100% of titanium grades). Low thermal conductivity and chemical reactivity: use rigid setups, sharp uncoated-carbide or AlTiN tools, 30–60 m/min, heavy flood coolant, and never dwell in the cut.
Can Ti-6Al-4V ELI (Grade 23) AM Powder POWDER be welded?
Yes — weldability is rated very good (75/100). Excellent by GTAW, laser and EBW under high-purity argon or vacuum with full back-purge; keep O/N/H pickup low and avoid porosity from residual powder or contamination.
What surface finishes work on Ti-6Al-4V ELI (Grade 23) AM Powder POWDER?
Support removal plus machining, abrasive/chemical polishing or electropolishing; anodize per AMS 2488 for color/bio-surfaces, or grit-blast/plasma-spray HA on implants.
Can Ti-6Al-4V ELI (Grade 23) AM Powder POWDER be formed, bent or molded?
Processed by L-PBF/EB-PBF/DED rather than forming; keep powder dry and O₂ controlled, orient parts to limit overhangs, stress relieve before removal from plate, and HIP for fatigue-rated parts.
What is the maximum service temperature of Ti-6Al-4V ELI (Grade 23) AM Powder POWDER?
Ti-6Al-4V ELI (Grade 23) AM Powder POWDER is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Ti-6Al-4V ELI (Grade 23) AM Powder-SR and Ti-6Al-4V ELI (Grade 23) AM Powder DED-HIP?
SR is the default condition — standard as-delivered condition for L-PBF parts: removes residual stress and distortion risk while keeping high strength. DED-HIP: use for large structural DED parts requiring certified fatigue and toughness (lack-of-fusion closure plus homogenised microstructure). Yield strength is 1,010 MPa in SR versus 865 MPa in DED-HIP.
