Frequently Asked Questions (FAQ)

1) What powder specifications matter most for Titanium Alloys Powder used in AM?

• Prioritize spherical morphology, PSD D10 15–20 µm, D50 25–35 µm, D90 40–50 µm; low satellites; interstitials tightly controlled (O ≤0.15 wt% for Ti-6Al-4V AM per many specs; ≤0.13 wt% for ELI variants; N ≤0.03 wt%; H ≤0.012 wt%); Hall/Carney flow within machine supplier limits; consistent apparent/tap density.

2) Gas atomization vs. PREP vs. HDH: which is best for different applications?

• Gas atomization (VIGA/EIGA) yields highly spherical, low-O powders ideal for LPBF/DED and MIM. PREP provides ultra-spherical, clean surfaces favored for EBM/critical aerospace parts but at higher cost. HDH is cost-effective for press-sinter/HIP billets; particles are angular with higher oxygen, typically not preferred for LPBF.

3) How should powder reuse be managed for Ti-6Al-4V?

• Implement sieving to spec each cycle, blend 20–30% virgin powder, track cumulative exposure hours, and monitor O/N/H and PSD tails. Set stop criteria (e.g., O increase ≥0.03 wt% from baseline, flow time +10–15%, or D90 drift >5 µm) and validate with density/fatigue checks.

4) Do titanium alloy parts always require HIP after LPBF/EBM?

• Not always. HIP is recommended for fatigue- or leak-critical components to close lack-of-fusion and gas porosity and improve HCF/LCF life. Non-critical parts with ≥99.5% density and benign defect morphologies can skip HIP after risk assessment.

5) What safety controls are essential when handling Titanium Alloys Powder?

• Maintain inert atmospheres (O2 typically <100 ppm in AM chambers), use explosion-protected equipment and grounded conductive tooling, avoid ignition sources, adopt Class D extinguishing media, and implement combustible dust housekeeping per NFPA 484/ATEX guidance.

2025 Industry Trends

• Ultra-low interstitial grades: Wider availability of ELI-grade Titanium Alloys Powder with O ≤0.12 wt% targeting implants and thin-wall lattices.
• Green/blue laser processing: Higher absorptivity enables denser Ti and copper–Ti hybrid builds with refined contour/remelt strategies.
• Traceability and data-rich CoAs: Lot genealogy, O/N/H trends, PSD raw data, and satellite indices standardize qualification for aerospace/medical.
• Sustainability: Argon recirculation, closed-loop powder handling, and certified powder reconditioning programs reduce total cost and emissions.
• Lattice allowables: Emerging fatigue design data for Ti-6Al-4V TPMS structures accelerates adoption in orthopedic and lightweight aerospace parts.
