Niobium-Tantalum Alloys

Description

Niobium has an excellent corrosion resistance in mineral acids, except in hydrofluoric acid, but in extremely corrosive media, like concentrated acids and-or at high temperatures, niobium is appreciably attacked. On the contrary, tantalum is practically unaffected in all acidic solutions, even concentrated and hot. Hence, tantalum, even if it is more expensive, is preferred to niobium for use in highly corrosive solutions. Niobium-Tantalum alloys are developed in order to obtain a material with better corrosion resistance than niobium and a lower price than tantalum. The advantages of these alloys include lower price, lower density, intermediary corrosion resistance between niobium and tantalum, ease to obtain as niobium and tantalum form a solid solution for all concentrations ease of fabrication of components due to the excellent ductility and ease of welding by Tungsten Inert Gas welding ^[1].
