Titanium Alloy Powder

All You Need To Know About 3D Printing Metal Powder Suppliers

3d metal printing powder

Titanium alloy powder is composed of titanium mixed with other metallic elements like aluminum, vanadium, iron, and molybdenum. The powders are made by gas atomization, a process that uses high-pressure gas to turn molten alloy into fine spherical particles ideal for additive manufacturing.

Titanium alloys offer the best strength-to-weight ratio of any metallic material. They are as strong as steel but 45% lighter. When produced as fine powders, titanium alloys become suitable feedstock for advanced manufacturing techniques like selective laser sintering (SLS), electron beam melting (EBM), and binder jetting. These methods allow intricate shapes and custom designs not possible with traditional fabrication.

Titanium and its alloys stand out for their corrosion resistance in harsh environments. They withstand saltwater, acids, and chlorine much better than aluminum, magnesium, or steel alloys. Titanium is also inert and non-toxic when implanted in the human body. This biocompatibility makes it invaluable for medical devices and implants.

With advanced properties like high strength, low density, corrosion resistance, and biocompatibility, titanium alloy powders enable lighter, stronger, longer-lasting parts across aerospace, automotive, medical, chemical, marine, and consumer industries.

Titanium Alloy Powder Composition

Titanium alloy powders contain primarily titanium along with alloying elements to improve strength, hardness, and high-temperature performance. The most common titanium alloys are Ti-6Al-4V, Ti-6Al-4V ELI, and Ti-3Al-2.5V.

AlloyComposition
Ti-6Al-4V90% titanium, 6% aluminum, 4% vanadium
Ti-6Al-4V ELI90% titanium, 6% aluminum, 4% vanadium, low interstitial impurities
Ti-3Al-2.5V95% titanium, 3% aluminum, 2.5% vanadium

Other alloying elements like iron, molybdenum, zirconium, tin, tantalum, or niobium may be present in small quantities. The composition is carefully controlled to achieve target properties after additive manufacturing.

The unique properties of titanium alloys in powder form enable advanced manufacturing, aerospace, medical, and other leading-edge applications.

The properties of printed parts depend on the additive manufacturing process as well as heat treatment after printing. For example, electron beam melting (EBM) generates finer microstructures and better mechanical properties compared to selective laser melting (SLM). Post-processing like hot isostatic pressing (HIP) can further enhance density, surface finish, dimensional accuracy, and material performance.

Some of the major application areas for titanium alloy powder include:

IndustryApplications
AerospaceEngine components, airframe parts, fasteners, hydraulic systems
MedicalImplants, surgical instruments, dental roots, braces
AutomotiveConnecting rods, valves, springs, fasteners, gears
ChemicalPumps, valves, pipes, heat exchangers, reaction vessels
Oil and gasDrill bits, completion tools, subsea components
Power generationTurbine blades, heat exchangers, steam and gas piping
Sporting goodsGolf clubs, bicycle frames, hockey sticks, lacrosse sticks
Consumer goodsWatches, glasses, jewelry, smartphones, cameras

Titanium alloys enable lightweight, high-performance designs across industries where strength, corrosion resistance, and biocompatibility are critical. The flexibility of powder metallurgy allows production of complex, net-shape parts not possible with conventional titanium mill products.

Titanium alloy powders are available in different size ranges, compositions, production methods, and purity levels. Here are some of the key specification parameters:

Specifications are based on ASTM B988 for gas atomized spherical titanium alloy powder and other international standards. Custom compositions and particle characteristics are also available for specialized applications.

Pricing for titanium alloy powder depends on many factors:

FactorImpact on Price
Alloy compositionHigher alloying content increases cost
Purity levelHigher purity grades are more expensive
Particle size distributionSmaller sizes are priced higher
Production methodPlasma and HDH powders cost more than gas atomized
Order quantityPrices decrease with larger order quantities
PackagingArgon purged sealed cans add cost

Some indicative price ranges:

  • Ti-6Al-4V powder 15-45 μm: $50-80/lb
  • Ti-6Al-4V powder 45-150 μm: $30-50/lb
  • Small lots in sealed cans are ~30% higher
  • Plasma Ti-6Al-4V powder: $120-150/lb
  • Purity grade 1 powder: $200-300/lb

Contact reputable suppliers like AP&C, Tekna, and Advanced Powders for quoted pricing based on your specific requirements. Be wary of low-cost powders from unknown sources with questionable quality.
