Titanium Alloy Powders

Titanium alloy powders demand tight oxygen, nitrogen and hydrogen control, with plasma or gas atomization, handling and reuse influencing interstitial pickup and fatigue-critical defects.

01

Definition and boundary

This page covers titanium powders as powder feedstock; it excludes automatic transfer of wrought or cast properties to consolidated parts.

Reference information only: final acceptance is controlled by the ordered product specification, condition, dimensions and certified test results.

02

How the material system works

01

Powder production controls morphology and interstitial pickup and hollow particles.

02

Particle-size distribution governs packing, spreading or compaction.

03

Consolidation route creates the final microstructure and defects.

Applications and selection

Applications and selection

  • aerospace and medical AM
  • Powder metallurgy components
  • Additive or spray processing

Properties and trade-offs

  • Choose process before PSD limits.
  • Qualify recycling exposure and alpha-case contamination.
  • Validate consolidated properties separately.

07

Fabrication, durability and inspection

01

Control recycling exposure and alpha-case contamination.

02

Use inert/dry handling appropriate to Titanium powders.

03

Apply documented sieving and reuse rules.

08

Procurement checklist

  • State Titanium powders alloy and powder production method.
  • Specify particle-size distribution (PSD) range/method, morphology, flow and apparent/tap density.
  • Define chemistry, oxygen/interstitial limits, sampling plan, lot blend and virgin/reuse history for Titanium powders.
