PowderRange®  Ti64 (Titanium-6% Aluminum-4% Vanadium, Ti-6Al-4V) is a high-performance titanium alloy characterized by excellent mechanical properties with a low specific weight and good corrosion resistance. Grade 23 (known as ELI) has lower limits for interstitial elements and is considered the higher purity version. Grade 23 displays increased ductility and fracture toughness with a slight reduction in strength over Grade 5, due to the reduction in interstitials. PowderRange® Ti64 complies to ASTM F3001.

One manufacturing method for Ti-6Al-4V powder is plasma atomization, resulting in superior sphericity and low residual elements such as oxygen, but introduces the risk of high-density inclusions that are inherent to the plasma atomization process. Certain gas atomization techniques such as EIGA, can also achieve comparable residual element levels with acceptable morphology for powder-bed additive machines. EIGA uses a method which is in a ceramic- and tungsten-free process which reduces the risk of high-density inclusions. PowderRange®Ti64 can be processed with argon shielding gas.

Additive manufacturing process guidance


Laser-Powder Bed Fusion(L-PBF) As-built

PowderRange Ti64 Grade 23 (ELI) is compatible with all commercially available L-PBF equipment.

To achieve mean, as-built density >99.9%, 20 to 60 μm layer thicknesses and Specific Energy ≥ 50 J/mm3 are recommended.

Stress Relieved (SR)

Stress relieve at 1100 ± 25°F (593 ± 14°C) for 2 hours under vacuum or argon atmosphere.

Hot Isostatic Pressedcondition (HIP)

PowderRange Ti64 is commonly used in the printed and HIP condition. We recommend HIP’ing the components on the build plate.

HIP is recommended for microstructure homogenization, removal of voids due to splatter, entrapped gas, and keyhole porosity, as well as shrinkage-induced micro-cracks in the material.

To achieve up to full density (100%): The nominal HIP parameters are as follows: HIP components under inert atmosphere at not less than 14.5 ksi (100 MPa) within the range of 1650 to 1750°F (900 to 955°C); hold at the selected temperature within ± 25°F (14°C) for 120 to 240 min, then cool under inert atmosphere to below 800°F (427°C). Follow with heat treatment as described above.


Additively manufactured PowderRange Ti64 machines similarly to wrought Ti-6Al-4V. The general recommendations for machining are to use rigid setups and low cutting speeds with heavy feed rates for rough machining. Work should be flushed with large volumes of non-chlorinated cutting fluid. Chlorinated fluids may be used if they are completely removed. Cemented carbide tools are recommended, and sharp tools should always be used. Feeding should not be stopped while tool and work are in moving contact.

Corrosion resistance

PowderRange® Ti64 immediately and spontaneously forms a stable, continuous, tightly adherent oxide film upon exposure to oxygen in air or water. This accounts for its excellent corrosion resistance in a variety of media. PowderRange®Ti64 is highly resistant to general corrosion in aqueous solutions including seawater, as well as in oxidizing acids, chlorides (in the presence of water), rocket propellants and alkalis. Conditions under which PowderRange® Ti64 is susceptible to general corrosion are in the presence of reducing acids or dry chlorine gas.
Stress-corrosion cracking (SCC) and crevice corrosion have been shown to occur in environments containing chlorides or other halide ions. For this reason, it is general practice to avoid the use of chlorinated solvents, cutting fluids, etc., in processing titanium.
Titanium and its alloys, including PowderRange® Ti64, are susceptible to hydrogen embrittlement. Gaseous or cathodic hydrogen can diffuse into the metal, forming brittle hydrides. Thus, it is important to minimize hydrogen pickup during processing, particularly heat treating and acid pickling. Specifications for PowderRange® Ti64 mill products typically specify a maximum hydrogen limit of approximately 150 ppm.


IMPORTANT NOTE: The following 4-level rating scale (Excellent, Good, Moderate, Restricted) is intended for comparative purposes only and is derived from experiences with wrought product. Additive manufactured material may perform differently; corrosion testing is recommended. Factors that affect corrosion resistance include temperature, concentration, pH, impurities, aeration, velocity, crevices, deposits, metallurgical condition, stress, surface finish, and dissimilar metal contact.
