tungsten is used to make the filament of bulb because of it's properties:
it has a rather high ignition temperature
it glows when an electric current passes through it
it breaks when there is overload of electricity in the circuit, thus, making the circuit
incomplete, so, no electric current passes through it.
tungsten has many strange properties which make it an ideal filament for a bulb
Tungsten, also known as wolfram, is an element with the symbol W and atomic number 74. Tungsten is as known as one of the heaviest materials except gold for the density of tungsten is 19.25 g•cm−3.
Tungsten is a typical element of transition element Group VI and shows oxidation states from +6 to-2 and, particularly in its oxides, forms many non-stoichiometric compounds. There is little aqueous chemistry except that of complex oxy-anions and some complex halides. The hexahalides are molecular but lower halides are polymeric and the lowest halides show extensive W-W bonding (more than Mo). Carbonyl and phosphine derivatives are typical low oxidation state compounds. Complexes are formed, particularly by O-and S-ligands in higher oxidation states and by P-ligands in low oxidation states. Complex cyanides are well established.
Tungsten is a Nonferrous Metal and is also Refractory. It is one of the most important Strategic Metals for IT industrial and military industrial.

It is a very hard metal.
It is denser than lead and almost as dense as gold.
It has the highest melting point of any metal
It is not reactive.
chronium, tungsten, and seaborgium
can you dissolve tungsten
Tungsten carbide products are often made from tungsten carbide powder cemented with another metal. This metal is often cobalt or nickel which is magnetic. 6% cobalt by weight is a typical percentage. Cobalt cemented tungsten carbide is magnetic enough to be picked up with a strong magnet. Tungsten carbide by itself would have very low to no ferromagnetic properties.
There are none, tungsten is a pure element so it is made of only tungsten.
Tungsten is found in wolframite (hence why the Germans called tungsten wolfram).

Yes, tungsten is a metal. This is from wikipedia A steel-gray metal, tungsten is found in several ores, including wolframite and scheelite. It is remarkable for its robust physical properties, especially the fact that it has the highest melting point of all the non-alloyed metals and the second highest of all the elements after carbon.
Tungsten comes under metals and has a steel-gray color. It has the highest melting point amongst metals. It is 19.3 times heavier than water and 71% heavier than lead. It is brittle and its alloys are used in the filament of incandescent bulbs.
Tungsten has a high melting temperature which allows it to carry the current needed to create an arc without melting. Other than that nothing else comes to mind. It is not highly conductive so has to be alloyed.
Tungsten is not Magnetic :(

That's tungsten. Wikipedia has more in their post on this amazing metal. A link to it is below.
