Answer:
Tungsten
Tungsten has a melting point at around 3400K, which is higher than any metal in pure form. And owing to its low thermal expansion, tungsten is able to maintain its form even when temperatures change drastically. This is why tungsten is used in the filaments of light bulbs.
the filament of an electric bulb is made up of tungsten and it's melting point is 3422°c
