Tungsten and it's applications:

Of all metals at temperatures above 1650 ^oC, Tungsten has the highest melting point (3422 ^oC) and the lowest vapour pressure of all metals. Tungsten is an excellent material for high-vacuum technology up to the highest temperatures. It is a very hard, heavy, steel-gray to white transition metal, tungsten is found in several ores including wolframite and scheelite and is remarkable for its robust physical properties, especially the fact that it has the highest melting point of all the non-alloyed metals.
