PowderRange Ti64 – Titanium Ti-6Al-4V Powdered Metal
Premium Titanium Alloy Powder for Additive Manufacturing & 3D Printing
Overview of PowderRange Ti64 Titanium-6Al-4V Alloy
PowderRange Ti64 (Titanium-6% Aluminum-4% Vanadium, Ti-6Al-4V) is a high-performance titanium alloy in Grade 23 (ELI – Extra Low Interstitials) form, engineered for advanced additive manufacturing applications. This exceptional material is characterized by excellent mechanical properties with a low specific weight and outstanding corrosion resistance, making it ideal for aerospace, medical, automotive, and energy applications demanding superior performance.
Grade 23 (ELI) is the higher purity version of Ti-6Al-4V with lower limits for interstitial elements (oxygen and nitrogen). This composition results in increased ductility and fracture toughness with only a slight reduction in strength compared to Grade 5, due to the reduction in interstitials. PowderRange Ti64 complies to ASTM F3001 specifications and offers excellent weldability in laser additive manufacturing processes. The combination of high strength-to-weight ratio, wear and corrosion resistance, fracture toughness, fatigue resistance, and excellent biocompatibility makes it the material of choice for mission-critical components.

- Hot Isostatic Pressing (HIP): 14.5 ksi (100 MPa) minimum within 1650–1750°F (900–955°C); hold at selected temperature ± 25°F (14°C) for 120–240 minutes, then cool under inert atmosphere to below 800°F (427°C)
- Recommended Condition: PowderRange Ti64 is commonly used in the printed and HIP condition for optimal mechanical properties
Corrosion Resistance & Environmental Performance
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. The material 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.
Stress-Corrosion Cracking & Hydrogen Embrittlement
Stress-corrosion cracking (SCC) and crevice corrosion can occur in environments containing chlorides or other halide ions. For this reason, it is general practice to avoid the use of chlorinated solvents and cutting fluids in processing titanium. PowderRange Ti64 is susceptible to hydrogen embrittlement. Gaseous or cathodic hydrogen can diffuse into the metal, forming brittle hydrides. Specifications typically specify a maximum hydrogen limit of approximately 150 ppm. Minimize hydrogen pickup during processing, particularly heat treating and acid pickling.
Important Note: The following ratings are for comparative purposes and derived from wrought material experience. Additive manufactured material may perform differently. Corrosion testing is recommended. Performance depends on temperature, concentration, pH, impurities, aeration, velocity, crevices, surface finish, and other factors.

Machinability Characteristics
Additively manufactured PowderRange Ti64 machines similarly to wrought Ti-6Al-4V. General recommendations include rigid setups, low cutting speeds with heavy feed rates for rough machining, and large volumes of non-chlorinated cutting fluid. 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.
