See the reference for details and the history. It has a reasonable electrical conductivity, is flexible, not brittle, lasts a long time in use, emits a minimum of material to darken the inside of the bulb, and is now reasonably economical to produce. But if you look hard enough, you'll probably find some other material used for some special purpose.

Because of its very high melting point, strength, and useful level of electrical conductivity.
