Like other refractory metals, niobium exhibits a very high melting point (2477 C); however, it stands apart from the other refractory metals due to its relatively low density.

Niobium applications

Thanks to its lower density, niobium is indispensable to the aerospace industry; offering high-performance physical properties in the form of a relatively lightweight and easily-worked metal.

Niobium alloys are used to manufacture superconducting magnets for use in medical MRI machines and NMR machines for analytical chemistry applications.

Boasting extremely low neutron absorption cross-sections and good resistance to liquid metals, niobium zirconium alloys are commonly used for structural elements in nuclear reactors.
