Hydride-Dehydride
Angular HDH titanium powder, CP Gr1-4 and Ti6Al4V, mesh to <20µm MIM cuts, O 0.15-0.45% selectable, H < 0.015% certified. Fraction of spherical powder cost.
QUICK ANSWER
HDH titanium powder is angular titanium powder made by hydrogenating titanium sponge or scrap, milling the brittle hydride, then dehydrogenating — the cost-effective route to CP titanium and Ti6Al4V powder for press-and-sinter powder metallurgy, MIM feedstock, thermal spray, and chemical applications. Where spherical gas-atomized powder is unaffordable or unnecessary, HDH delivers titanium's properties at a fraction of the powder cost.
HDH powder is angular and irregular — it flows poorly but presses beautifully, particles interlocking into strong green compacts that sinter to 95-99% density. This makes it the backbone of titanium press-and-sinter PM: CP titanium and Ti6Al4V parts for chemical, marine, medical, and consumer applications where full machining from billet wastes 80% of expensive material. MIM producers blend fine HDH cuts with binder for titanium injection molding at cost levels unreachable with spherical powder. The trade-offs are oxygen content (HDH runs higher than atomized, affecting ductility) and shape (unsuited to LPBF) — specifications buyers must match to process.
MATERIAL DATA
Lot-level controls focus on the chemistry, particle characteristics, and process values that influence manufacturing consistency and finished-part performance.
| Element | Content | Performance Role |
|---|---|---|
| Titanium (Ti) | > 99.5 wt% (CP grades) / Ti6Al4V alloy | Base purity — CP1-CP4 and alloy grades |
| Oxygen (O) | 0.15-0.45 wt% (grade dependent) | Key spec — sets strength/ductility balance of sintered parts |
| Hydrogen (H) | < 0.015 wt% (dehydrided) | Residual H embrittles — certified removal |
| Iron (Fe) | < 0.3 wt% | CP grade limits |
| Chloride residue | < 0.1 wt% | Sponge-route residue control |
Final limits can be aligned with the agreed purchase specification.
APPLICATIONS
Titanium press-and-sinter PM is the core market: sintered titanium valves, fittings, fasteners, and structural parts serve chemical processing (corrosion immunity), marine hardware, and increasingly consumer electronics and sporting goods — anywhere titanium's strength-to-weight and corrosion story justifies material cost but machining waste does not. HDH powder presses and sinters in standard PM equipment, and part producers buy on oxygen content (it sets the sintered ductility), size distribution, and lot consistency.
MIM and advanced routes form the growth market: titanium MIM using fine HDH cuts (<45 µm, <20 µm) produces small complex parts — watch cases, medical components, firearm parts — at costs that opened titanium to volume consumer markets. Thermal spray and laser cladding use HDH cuts for titanium coatings; chemical and pyrotechnic-grade titanium (sponge fines, specified cuts) serves getter, ignition, and alloy-addition roles. Emerging consolidation routes — spark plasma sintering, field-assisted pressing — favor HDH's clean sintering behavior.

Oxygen is titanium's strength dial: 0.15-0.25% O gives ductile parts (CP Gr1-2 equivalent); 0.30-0.45% gives strength at ductility cost (Gr3-4 equivalent). Tell us your sintered property target and we match the lot.
Yes — fine cuts below 45 µm and 20 µm serve titanium MIM feedstock, widely used for watch and medical parts. Oxygen and interstitial control are tighter for MIM; we supply MIM-specific grades.
95-99% density with vacuum sintering at 1200-1300 °C; CP titanium parts reach wrought-equivalent corrosion resistance and 80-95% of wrought mechanical properties. We provide sintering windows per grade.
Yes — hydrogen above ~0.015% embrittles titanium. Our dehydride cycle and certification keep H below specification; the data ships with every lot.
No. Titanium powders ship without licensing requirements.
