Molybdenum, Niobium

Tantalum is an element with a very high melting point with excellent deep-drawing properties. In addition to its superior ability to be fabricated, its temperature from ductile to brittle is low. Tantalum’s most common use is in electrolytic capacitors. Another use is chemical process equipment such as heat exchangers and condensers. The aerospace and nuclear industries have found a variety of applications for the metal. Because it has good corrosion resistance and resistance to bodily fluids, it can be used for prosthetics and surgical devices.
