At 3,420 o C, tungsten has the highest melting point of all metals. In fact, at that temperature most other metals have already vaporised. Its boiling point at around 5,700 o C is the same temperature as the surface of the sun. Pure tungsten is quite workable, but it usually contains minor amounts of oxygen and carbon, which makes it very hard.
