Spherical tantalum feed powder for metal additive manufacturing

Abstract

Tantalum is the new “T” metal for additive manufacturing (AM) applications. Metal AM has seen significant growth over the last few years with key drivers coming from the aerospace, medical and dental industries. The metal landscape for AM in these industries has been largely dominated by titanium, nickel alloys and steel alloys. Development of new metals for AM processes in these and other industries is vital for full realization of the capability of this technology. Tantalum, for example, has high ductility, superb corrosion resistance and superior biocompatibility. Global Advanced Metals, a leader for almost 70 years in the production of tantalum and niobium products, has developed tantalum feeds for a range of AM processes. GAM’s spheroidization of raw powders using a plasma technology results in excellent flow properties and high packing density. Test parts and coupons have also been successfully printed via Laser-Powder Bed Fusion process. The physical properties of the printed tantalum confirm suitability for a wide variety of applications including aerospace, medical and dental industries.
