Product description

Osprey^® Ti-6Al-4V-ELI* (Grade 23) is a titanium grade alloyed with aluminium and vanadium, especially developed for Additive Manufacturing (according to ASTM F3001-14), as well as for Hot Isostatic Pressing (HIP).

The grade is characterized by high strength, very good corrosion resistance and low density. It is similar to Osprey^® Ti-6Al-4V (Grade 5) but has a lower content of oxygen, nitrogen and iron, resulting in, for example, higher ductility. Osprey® Ti-6Al-4V-ELI (Grade 23) is typically used for medical implants as well as for aerospace and chemical processing applications.

Osprey^® titanium powder is manufactured to the highest international quality management standards, for example, AS9100D (aerospace) and ISO 13485:2016 (medical).

SEM micrographs of -63 +20 µm powder with a spherical morphology (HS Circularity 0.95), smooth surface and low level of powder satellites (magnifications x100 and x250) and a section through the powder (magnification x1000), with no visible internal porosity.

Particle size distribution

Powder for Additive Manufacturing

Osprey^® metal powder for Additive Manufacturing is available in a wide range of particle size distributions that are tailored to the individual Additive Manufacturing systems. They can also be tailored to the particular requirements of the end application, both in terms of mechanical performance and surface finish.

Typical particle size distributions for Additive Manufacturing.

Typical particle size distributions for Additive Manufacturing
Process technology	Size (µm)
Binder jetting	≤ 16, ≤ 22, ≤ 32, ≤ 38, ≤ 45
Laser - Powder Bed Fusion (L-PBF)	15 to 53 and 10 to 45
Electron beam - Powder Bed Fusion (E-PBF)	45 to 106
Direct Energy Deposition (DED)	53 to 150

Powder for Hot Isostatic Pressing (HIP)

Osprey^® powder for Hot Isostatic Pressing (HIP) is available in a broad size range, typically <250 microns, resulting in a high packing density and tap density. Low oxygen levels, together with high packing density, also facilitate faster sintering.

Powder for Metal Injection Moulding (MIM)

Osprey^® metal powder for Metal Injection Moulding (MIM) is available in a wide range of particle size distributions, from under 5 μm up to 38 μm. The table shows our standard particle size distributions for MIM powders.

Microstructure

SEM micrographs of Osprey^®TI-6AL-4V-ELI (Grade 23) Laser - Powder Bed Fusion (L-PBF) material in a heat-treated condition (solution annealed at 850 °C/1,562 °F for 2h in argon) on the left, featuring a fine lamellar and dense microstructure is identified which originates from the decomposition of martensitic α’ as expected; showing a phase transformation that gave rise to a coarser structure consisting of a α phase matrix (grey) and an interlamellar β phase (bright).

The difference in microstructure for vertical and horizontal builds is not significant. The mechanical properties of heat-treated L-PBF material are provided below. The microstructure, shown on the right, for L-PBF material after Hot Isostatic Pressing (HIP), which results in a coarsening of the grain size. The mechanical properties of HIP material are similar to that of the heat-treated material with an improvement in impact toughness, especially in the vertical direction.
