Applications

Metal Additive Manufacturing / 3D Printing

Spherical tantalum powder can be used as feedstock for producing complex tantalum components through laser- and electron-beam-based additive manufacturing processes.

Metal Injection Molding

Fine spherical tantalum powders can be considered for MIM applications where powder packing, flow characteristics, and controlled particle size are important.

Powder Metallurgy

Spherical Ta powder can be consolidated using powder-metallurgy processes to produce tantalum components and near-net-shape parts.

Thermal Spraying

Selected particle size distributions can be supplied for thermal spray and related surface-engineering processes.

Medical and Biomedical Research

Tantalum is used in biomedical materials research and medical-device applications. For medical projects, customers should specify the required purity, particle size, impurity limits, documentation, and applicable regulatory or material requirements.

Aerospace and High-Temperature Applications

Tantalum's refractory characteristics make it useful in research and manufacturing involving high-temperature and demanding environments.

Spherical Tantalum (Ta) Powder Storage and Packaging
