Titanium Powder

AmeriTi Powder

Titanium powder has long been used as an alloying additive for a variety of applications. Recently, technological advances in the production and use of titanium powder have opened doors into many fields including powder metallurgy, thermal spray, laser cladding, metal injection molding, and additive manufacturing.

AmeriTi Manufacturing produces titanium powder using the hydride-dehydride (HDH) process. This method uses hydrogen to make the titanium brittle enough to crush and perform initial sizing. Hydrogen is then removed under vacuum followed by final sizing to customer specifications. This process creates a final particle morphology described as blocky or angular.

AMC also has the capability to deoxidize titanium alloy powders. Titanium is extremely reactive with oxygen causing it to inevitably increase in oxygen throughout the powder manufacturing process. Our patented deoxidation process allows for possible oxygen levels below 1000 PPM, which is necessary for grades such as Ti 6Al-4V ELI. Deoxidation services are performed on AmeriTi produced titanium powder, but is also available as a toll processing service.

Using this process, AmeriTi is able to produce both commercially pure and alloyed titanium powder in a wide range of particle sizes. Screening and blending processes ensure accurate sizing to customer specifications. Advanced process controls and in-process testing allow for consistent particle size distributions and morphology from lot to lot.

Our on-site laboratory enables AmeriTi to effectively test and certify powder chemistry and powder sizing. Particle morphology can be certified as well using a local, A2LA accredited 3rd party lab.


HDH Process

Raw Materials

Raw materials are purchased to specification, inspected upon receipt, and stored.

Crushing and Initial Sizing

Depending on raw material type and size requirement several milling or crushing equipment options are available. The crushed particles are sized using advanced sieving techniques.

Final Sizing

Titanium powder can be further crushed or milled if needed and then final particle size distributions are created through sieving.

Hydride Process

Raw material is heated under vacuum to a set temperature and hydrogen gas is introduced to create a hydrogen partial pressure atmosphere. Hydrogen diffuses into the titanium to form a brittle titanium hydride (TiH2).

Dehydride Process

Sized TiH2 heated under vacuum to a set temperature for hydrogen removal.

Final Testing and Packaging

Material is inspected per customer specification and packed to ship.


Grades and Sizes

Sizing

Available particle sizes range from 425µm down to sub 10µm. Customer specified size distributions can be met via sieve or laser particle size analysis (Malvern/MicroTrac). Both capabilities are in-house. Particles outside of this range may be available upon request.

Grades

Commercially Pure (CP) Titanium

AmeriTi currently offers CP Grade 1 through 4. Raw materials for CP grades are wrought (plate, bar, etc) or sponge (Kroll and Hunter). The different raw materials provide different particle morphology, which results in different properties. For questions on the difference between raw materials please submit a contact to Jake Sloan from the contacts page.

Titanium Alloys
  • Ti 6-4 Grade 5
  • Ti 6-4 Grade 23 (ELI)
  • Ti 10-2-3
  • Ti 21S
  • Ti 6-2-4-2
  • Ti 6-2-4-6
Enriched Titanium Alloys

AmeriTi has the unique ability to supply enriched alloy powder. This includes enriching powder with alloying elements that are lost during post-processing steps. An example of this is an enriched aluminum version of Ti 6-4 to compensate for aluminum loss during direct metal laser sintering or selective laser melting additive manufacturing.
