Appearance:  Tungsten has the highest melting point of all metals, and because of this it is used for the filaments of light bulbs. It is alloyed with other metals to strengthen them

Uses:  Tungsten and its alloys are used extensively for filaments for electric lamps, electron tubes and television tubes. As it has the highest melting point of all metals it is used in numerous high-temperature applications. High-speed tool steels contain tungsten, as does a new “painless” dental drill which spins at ultra-high speeds. Tungsten carbide is immensely hard and is of great importance to the metal-working, mining and petroleum industries. Calcium and magnesium tungstates are widely used in fluorescent lighting.

Biological role:  Tungsten has no known biological role, and has low toxicity.

Space-age super-alloys

Light bulb filaments - fluorescent lighting

Cemented carbides (also called hardmetals)

Armaments

Jewelry - Tungsten Carbide

Interesting facts:  tungsten has the highest melting point out of all the elements. 

Tungsten is also used in lightbulbs that we are constantly using.

It is also used in jewelry.
