Spherical Tantalum Tungsten (Ta-W) Alloy Powder

Spherical Tantalum Tungsten Alloy Powder Description

Heeger Materials supplies high-purity Spherical Tantalum Tungsten (Ta-W) Alloy Powder for additive manufacturing, powder metallurgy, thermal spraying, laser cladding, and advanced refractory-metal research.

Our Ta-W spherical powders combine the high-temperature and corrosion-resistant characteristics of tantalum with the strengthening effect of tungsten. Available grades include Ta-2.5W, Ta-5.5W, Ta-7.5W, and Ta-10W.

The powders feature high sphericity, low oxygen content, controlled particle size distribution, good flowability, and high apparent and tap density, making them suitable for demanding powder-based manufacturing processes.

Standard particle size ranges include 5–25 μm, 15–45 μm, 15–53 μm, 45–75 μm, 45–105 μm, and 75–150 μm. Custom particle size distributions are available upon request.

Available Ta-W Alloy Grades

Ta-2.5W

Ta-2.5W contains approximately 2.5% tungsten and offers a balance of increased strength and good processing characteristics compared with pure tantalum.

Ta-5.5W

Ta-5.5W provides an intermediate tungsten content for applications requiring higher strengthening while retaining tantalum-based refractory-metal characteristics.

Ta-7.5W

Ta-7.5W offers a higher tungsten level for applications requiring increased mechanical strength and high-temperature performance.

Ta-10W

Ta-10W contains approximately 10% tungsten and provides the highest tungsten content among the standard Ta-W spherical powder grades listed on this page.

Spherical Ta-W Powder for Additive Manufacturing

Spherical tantalum tungsten alloy powder is suitable for additive manufacturing processes where powder morphology, flowability, chemistry, and particle size distribution are critical.

Potential processes include:

• Laser Powder Bed Fusion (LPBF / SLM)
• Electron Beam Melting (EBM)
• Directed Energy Deposition (DED)
• Other powder-fed additive manufacturing processes

High sphericity and controlled PSD can support consistent powder feeding and layer formation, while low oxygen content is important for maintaining material quality in tantalum-based refractory alloys.

The appropriate PSD should be selected according to the specific equipment, layer thickness, and process parameters.

Particle Size Options

Standard particle size ranges include:

• 5–25 μm
• 15–45 μm
• 15–53 μm
• 45–75 μm
• 45–105 μm
• 75–150 μm

Custom D10, D50, and D90 specifications can be reviewed according to customer requirements.

Applications

Additive Manufacturing

Used as feedstock for Ta-W alloy components manufactured by LPBF, EBM, DED, and related metal additive manufacturing processes.

Powder Metallurgy
