What Are the Uses of Tantalum and Tantalum Alloys?
What Are the Uses of Tantalum and Its Alloys? Tantalum is the third most refractory metal, with a melting point of 2980℃, only after tungsten and rhenium.Besides, tantalum also has other excellent properties like low vapor pressure, good cold workability, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of the surface oxide film.Get PriceEmail contact

niobium development. The niobium (columbium until late 1970’s) ore was at one point considered so crucial to the war (WWII) effort that it was reportedly flown into the country rather than risk loss at sea (4). For some time the extraction of niobium was dependent upon being a bi-product of tantalum refining.Get PriceEmail contact
