The main applications of this metal are due to its inert chemical properties, resistance, hardness and ductility; thus, it is used in the production of chemical equipment with resistance to corrosion, or in high temperatures ovens, filaments for light bulbs, canalizations for switches of liquid metals in nuclear reactors, surgical instruments and implants, etc.

The electrical properties of tantalum oxide made it useful in the production of rectifiers and capacitors. Tantalum carbide is used in the production of sharp instruments, with extreme mechanical resistance and hardness.
