Refractory Metalan overview ScienceDirect Topics
A narrowly defined class of refractory metals would include metals with melting points > 2000°C niobium chromium molybdenum tantalum tungsten and rhenium 1 while a wider class would also include those with melting points above 1850°C vanadium hafnium titanium zirconium ruthenium osmium rhodium and iridium. The current practical application of refractory metals is relatively widespread

Nobium Alloys Properties Applications
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. At only 8.57g/cm 3 niobium has a density similar to that of nickel and copper making it the lightest of the refractory metals.
