Melting Point: 3680 K (3407 degrees C)
Boiling Point: 5930 K (5657 degrees C)
Enthalpy of Fusion: 35.2 kJ/mol
Enthalpy of Vaporisation: 824.2 kJ/mol
Gasseous Tungsten vapor can withstand even more heat.
Ionization energy to first ionization: 770 kJ/mol
(others are listed up to +6 if you are curious)
