Niob Bars (Nb-Bars) Applications
Aerospace Industry: Owing to its high strength and resistance to elevated temperatures, niob is utilised in components for jet engines and spacecraft, thereby ensuring reliable operation under extreme conditions.
Electronics: Due to its excellent electrical conductivity, niob is employed in the manufacture of capacitors and other electronic components.
Superalloys: Niob is added to steel and other metals to produce superalloys required for high temperature applications such as turbines and nuclear reactors.
Medical Devices: Given its biocompatibility, niob is used for medical implants and devices that meet safety and compatibility requirements with the human body.
Optical Applications: Niob is applied as a coating on glass for camera lenses and other optical instruments to improve light transmission and wear resistance.
