Titanium Alloy Powder
All You Need To Know About 3D Printing Metal Powder Suppliers
Product Category
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.
| Alloy | Composition |
|---|---|
| Ti-6Al-4V | 90% titanium, 6% aluminum, 4% vanadium |
| Ti-6Al-4V ELI | 90% titanium, 6% aluminum, 4% vanadium, low interstitial impurities |
| Ti-3Al-2.5V | 95% 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.
Properties of Titanium Alloy Powder
The unique properties of titanium alloys in powder form enable advanced manufacturing, aerospace, medical, and other leading-edge applications.

| Fracture Toughness | 75 MPa-m^1/2 | 60 MPa-m^1/2 | 65 MPa-m^1/2 |
| Thermal Conductivity | 7 W/m-K | 7 W/m-K | 6.7 W/m-K |
| Electrical Resistivity | 170-190 μΩ-cm | 170-190 μΩ-cm | 172 μΩ-cm |
| Coefficient of Thermal Expansion | 8.6 μm/m-°C | 8.6 μm/m-°C | 8.8 μm/m-°C |
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.
Applications of Titanium Alloy Powder
Some of the major application areas for titanium alloy powder include:
| Industry | Applications |
