Why tungsten is not used as a fuse wire

Answered by admin @ 17/08/2021

Tungsten forms important part of the filament as it has a high melting point. In addition, the metal is immune to corrosion due to excessive heat.

The lowest thermal expansion plays a very important role in enhancing the durability of the tungsten by many notches.

Tungsten is inactive to other gasses.
