Which metal has the highest melting point of any metal and is commonly used for the filament inside traditional incandescent light bulbs?

Explanation

Tungsten has the highest melting point of any metal, at approximately 3,422 degrees Celsius, which is precisely why it has traditionally been used for the thin filament inside incandescent light bulbs, since the filament must withstand extremely high temperatures without melting while glowing brightly. This exceptional heat resistance also makes tungsten useful in various other high-temperature industrial applications. Despite this valuable property, incandescent bulbs using tungsten filaments have increasingly been replaced in many markets by more energy-efficient LED lighting technology.
