Custom Aluminum Alloys
- Kymera International leads the industry, offering the broadest range of alloying flexibility of any aluminum powder producer. With production ranging from 5 pounds to 5 tons, we are your preferred partner for new product development.
Titanium powders are in highest demand for lightweight applications requiring high strength properties. Through collaborations with industry and university partners, Kymera has undergone a significant amount of development of non-spherical titanium powders for laser additive manufacturing. Melt-free titanium powders are suitable for laser additive and designed to lower overall material costs per part. Our powders are produced using a high volume process and are qualified for many demanding applications, including orthopedic implants.
We supply CP Ti powder for use in additive manufacturing applications. The hydride / de-hydride (HDH) process forms highly pure Ti with an angular shape which maintains powder flow.
Titanium powders are lightweight, strong and corrosion resistant and used in a wide range of today’s most demanding markets. Our titanium powders are produced via a proprietary hydride / de-hydride (HDH) process.
Additively manufactured parts made from refractory metals can withstand high heat applications. Not only are these metals extremely resistant to heat and corrosion, they also retain their structural integrity even at elevated temperatures. These powders are ideal in demanding aerospace and industrial applications. Refractory metals are quite difficult to process via traditional fabrication methods, thus additive manufacturing methods are proving to be extremely beneficial for such high-heat bearing applications. Using spherical refractory metal powders from Kymera International will help industry overcome historical manufacturing limitations by increasing design flexibility, providing new material options, providing more cost effective solutions and decreasing time to market.
- Molybdenum is the sixth-highest melting point element. Kymera International offers spherical, high-purity powder.
- Rhenium has the third-highest melting point of any element and is used in extreme temperature applications and as a catalyst. Spherical rhenium powder from Kymera International has ultra-low impurity levels.
Spherical Tungsten Powder
- Tungsten has the highest melting point of all known elements. Because it is difficult to process tungsten by conventional methods, additive manufacturing using highly spherical powder with low impurities from Kymera International offers unprecedented design freedom.
- TZM is a molybdenum alloy containing titanium and zirconium which has higher strength and creep resistance than pure molybdenum and resists high-temperature embrittlement.
- C103 is a niobium alloy with additions of hafnium and titanium with extreme temperature resistance for use in aerospace and harsh environments.
Kymera is focused on partnering for the development and commercialization of stainless steel powders for additive manufacturing. These powders are produced by proprietary methods to achieve the highest performance and most cost competitive materials on the market.
- 304L is the most commonly produced stainless steel and is used in food preparation, consumer goods, automotive and architectural applications. It is however, susceptible to corrosion attack in marine environments, where 316L becomes the favored alloy.
- After 304L, 316L is the second most commonly produced stainless steel. With very high resistance to chemical attack, 316L is used in marine environments, chemical processing, food preparation, and medical devices.
- Containing Ni and Cu additions, 17-4 is a precipitation hardened stainless steel, with higher strength, corrosion resistant, and thermal stability compared to 304L. For this reason, it is used in more demanding applications.

Metal Binder Jetting
Binder jet additive manufacturing provides a unique advantage to the AM market over alternative print methods such as selective laser melting (SLM) or laser powder bed fusion (LPBF) for reactive metals. Because of the reactive behavior of aluminum, its alloys were traditionally limited to casting grades for the slower SLM-based processes. Kymera is now able to process dedicated aluminum alloys quickly by binder jetting.
Binder jet printing involves spreading a layer of powder and applying droplets of binder to form a consistent green part. By filling the entire volume of the print box with highly engineered metal powder, printing without supports is realized. This offers more design freedom to the user, allows more parts to be packed into a build and requires no post-process to remove supports. These benefits, coupled with production speeds much faster than laser powder bed fusion, make binder jetting more practical to scale to high volume production. In addition, any powder that has not been bound with the binder solution is able to be recycled for use again in future prints, leading to more efficient use of material, reducing additional energy and carbon emissions costs.
Kymera offers many aluminum, copper, titanium and stainless steel alloys for binder jet. Common particle sizes include <15, <28, <36, <45, <63 and <75 micrometers.
Powder Bed Fusion
Kymera has extensive experience developing and producing powders for use in powder bed fusion applications. Powder bed fusion technology offers several variants designated by the heat source used and type of material joined. The predominant types are laser beam and electron beam.
Selective laser sintering (SLS) is a process which typically sinters powdered polymer materials. Selective laser melting (SLM) is similar to SLS, however the laser fully melts the powder rather than sintering it. This process is more commonly applied to metal powders including Kymera’s aluminum alloys, titanium and titanium alloys, copper and stainless steel. Electron beam melting (EBM) is comparable to SLM, replacing the laser with an electron gun, requiring a vacuum chamber instead of an inert atmosphere.
Powder bed fusion applications provide full customization, reduced material waste and cost, improved development times, rapid prototyping and low volume production and efficient recycling of un-melted powder.
Kymera offers many aluminum, copper, titanium, stainless steel and refractory metals and alloys for powder bed fusion. Common particle sizes include 15-45, 20-63, 25-75 and 45-106 micrometers.
Directed Energy Deposition
Kymera’s additive manufacturing materials can be found in numerous directed energy deposition (DED) applications. Using a focused energy source, such as an electron beam, laser or plasma arc, DED melts a material which is simultaneously deposited by a nozzle. The energy is directed toward a plate or substrate material where it impacts a wire or powder feedstock, melting and leaving the deposited material attached to the substrate. DED has a higher deposition rate than other AM processes and generally is able to produce larger parts that wouldn’t fit within a powder bed system.
Kymera offers many aluminum, copper, titanium, stainless steel and refractory metals and alloys for DED. Common particle sizes include 15-45, 20-63, 25-75 and 45-106 micrometers.
Cold spray additive manufacturing enables the fabrication of freestanding parts or the building of features on existing components. During the cold spray process, fine powder particles, such as those produced by Kymera, are accelerated in a high-velocity compressed gas stream. Upon impacting the substrate or backing plate, the particles deform and bond together creating a layer. As the nozzle moves, a part is formed layer-by-layer. The cold spray process can be advantageous due to its high deposition rates, uncontrolled environment, ability to combine dissimilar materials, possibility of producing much larger scale parts and ability to collect and reuse spare particles.
Kymera offers many aluminum, copper, titanium and stainless steel alloys for cold spray. Common particle sizes include 15-45, 20-63, 25-75 and 45-106 micrometers.
