Nichrome wire is commonly used for resistance wire for heater elements and it is a non-magnetic alloy of two elements nickel and chromium. It has high resistance and resists oxidation. The electrical resistivity is about 65 times that of copper.
They're made of Tungsten.
The filament is usually made from wolfram (W) and the filling gas is argon.
Incandescent light bulbs use a tungsten filament as the element that emits light when heated by an electric current.

Tungsten
Tungsten is typically used as the filament in incandescent light bulbs because of its high melting point and ability to emit light efficiently when heated by an electric current.
Tungsten is an element. It is used in bulbs
In the old style filament lightbulbs it was tungsten (wolfram).
An immersion electric heater usually uses nichrome wire as the heating element. Nichrome is highly resistive, and by applying a voltage, we can get it pretty hot. Nichrome is used as the heating element in toasters and on electric range elements as well as lots of other places.
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Usually tungsten.
The main feature of an efficient electric heater is, that is used up to 30% less engery than a conventional electric heater. This reduces the cost of the heater.
