What Is Tungsten Filament?
【Chinatungsten Online News Net- Tungsten News】
A tungsten filament is a thin strand of the metal which glows very brightly when an electric current is passed through it. When coiled and sealed inside a glass container filled with an inert gas, a tungsten filament can glow brightly enough to light up a room. It was the inclusion of a tungsten filament in his electrical lighting system that resulted in the world giving Thomas Edison credit for inventing the electric light bulb when in fact dozens of scientists had been experimenting with electric light.
Tungsten is an element (Symbol: W; Atomic Number 74) discovered in the late 18th century. Almost twice as dense as lead, it has the highest melting point of all the metals at 6192 ° F (3422 ° C); of all the elements, only carbon’s melting point is higher. These properties make tungsten very useful not only in electric technology, but also for military applications such as hardening weapons. Another use of tungsten is as a component of jewelry, where it’s combined with other materials to form very hard and lustrous compounds, although they can be brittle.
