H.C. Starck Tantalum and Niobium GmbH, Goslar, Germany, has launched its new range of atomised tantalum and niobium powders and alloys designed specifically for metal AM processes, first announced in October. Under the brand name AMtrinsic®, the new powders are suitable for a wide range of demanding applications.
The powder systems under the new brand AMtrinsic include elemental Ta/Nb powders and range from binary over complex multinary to high-entropy alloys also in customer specific compositions. Besides Ta and Nb, alloying elements include but are not limited to Ti, Zr, Hf, Mo, W, V, Sn, and Al.
Tantalum and niobium, as well as alloys containing these elements, offer a unique set of properties including high melting point, high corrosion resistance, excellent chemical resistance and high thermal and electrical conductivity. This makes them ideal for high-tech applications in fields such as chemical processing, superconductors, energy and high-temperature environments.
“With this new brand we express our approach to provide powders that allow to combine the unique intrinsic material properties of tantalum and niobium and their alloys with the geometric design freedom offered by additive manufacturing technologies,” stated Dr Melanie Stenzel, H.C. Starck Tantalum and Niobium’s Head of Marketing and new Business Development.
In addition, parts additively manufactured from Ta/Nb containing alloys may offer an alternative for the optimisation of mechanical and biological performance parameters in medical implants. Multinary alloy compositions or high-entropy alloys containing Ta/Nb are said to be especially of interest for the design of completely new intrinsic material properties that can provide superior solutions in challenging applications, especially when combined with the freedom of geometric design available using AM.
Dr Kazuyuki Marukawa, Vice Chairman H.C. Starck Tantalum and Niobium, added, “We are very much looking forward to taking this exciting path in further strengthening our position in the field of Additive Manufacturing metal powders and continuous powder developments with our customers and research partners.” H.C. Starck Tantalum and Niobium will present the AMtrinsic brand at Formnext 2019 in Frankfurt, Germany, November 19–22.
