That depends on the bulb, and the time frame. The first bulbs had carbon filaments. Certain bulbs used in control devices have iridium filaments. Modern grocery store incandescent bulbs have tungsten filaments.Tungsten, because of its very high melting point.

Argon(or nitrogen) and tungsten are used in incandescent light bulbs.
Most incandescent bulbs have one filament. Some halogen bulbs working on 240 v have two filaments in series, which must be to simplify manufacture of bulbs being made for 120 v and 240 v in the same factory.
Tungsten is the main one. There may be others.
Tungsten is used in filaments of light bulbs.
Incandescent bulbs.
In an incandescent light bulb (the kind that screws into a standard light socket), the filament is the piece of metal in about the middle of the glass bulb that glows and emits light and heat when electricity passes through it. It is usually made of tungsten, but originally was made of carbon. New compact fluorescent and LED-based light bulbs do not really have filaments like incandescent light bulbs. Filament is a term also used in astronomy and biology for different things, but these uses are not as common as in light bulbs.
There is nothing that states incandescent light bulbs will one day be illegal or outlawed. Using them is an individuals option and right.
