In short: Ti6Al4V (Grade 5, TC4) is an alpha-beta titanium alloy with 6 % aluminium and 4 % vanadium. With a density of about 4.43 g/cm³, a high strength-to-weight ratio and corrosion resistance, it is the most widely used titanium powder in metal 3D printing. The low-interstitial ELI (Grade 23) grade is evaluated separately for implants.
Typical applications
- Aerospace brackets and structural parts
- Medical implant and instrument development (ELI grade)
- Motorsport and bicycle components
- Lightweight defence parts

Particle size and compatible processes
The standard cut is 15–53 µm, suitable for laser powder bed fusion (LPBF / SLM / DMLS) machines. Coarser cuts for DED/LMD processes can be requested. Share your machine model and layer thickness and we will confirm the right cut and batch documents together.
Frequently asked questions
What is the difference between Ti6Al4V and Ti6Al4V ELI (Grade 23)?
ELI (Extra Low Interstitial) has lower oxygen, nitrogen and iron, improving toughness and fatigue behaviour. Medical implants generally use the ELI grade (ASTM F3001 reference).
How should titanium powder be stored?
In closed, argon-filled containers in a dry area. Track oxygen pick-up over reuse cycles; fine titanium powder is combustible, so ATEX rules apply.
Ti6Al4V powder price: what does it depend on?
The price depends on order quantity (kg), particle size cut, packaging (argon-filled cans or bottles), required documents (certificate of analysis, PSD report) and lead time. For a current price, state the quantity and your machine model in the quote form.
Which documents come with the order?
A certificate of analysis with chemical composition, particle size distribution (D10/D50/D90), flow and density values can be requested for each batch. Additional documents for aerospace, medical or dental projects are confirmed at the quotation stage.
