What material is used to make the filament of a household bulb?

The filament of a household bulb is typically made from tungsten. Tungsten is chosen for its high melting point and ability to withstand high temperatures without melting, allowing it to produce light effectively when electric current passes through it. In some energy-efficient bulbs, such as CFLs or LEDs, different technologies are used, but traditional incandescent bulbs primarily rely on tungsten filaments.
