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
