Appearance of tungsten wire:
The tungsten wire is coated with colloidal graphite on the surface and tungsten appears uniform black. Tungsten wire appears metal luster if being removed colloidal graphite.
Tungsten wire supply:
We supply pure tungsten wire, tantalum tungsten alloy wire, tungsten copper alloy wire and other tungsten alloy wire. Our tungsten wire supply ability is 10 tons per month.
The delivery time of tungsten wire is 7 to 30 days after confirmation.
Tungsten wire is the best material to make lamp bulb.
In our daily life, there are a lot of metals that can give light besides tungsten filament light bulb, such as copper wire, iron wire, etc.. While, why do we select the tungsten material as the luminous body of bulb? Zhengzhou Sanhui Co., Ltd will explain how tungsten wire give out light to you?
Because the tungsten filament has relatively high electric resistance and melting point, when the electric current goes through the tungsten wire, the electric resistance of tungsten wire rises and gives out heat, then tungsten wire and tungsten alloy wire give out light. At the same time, the melting point of tungsten wire is very high, so tungsten wire is not easily to be burnt out. In addition, inert gas- neon is filled in the bulb, which ensures tungsten wire is not able to be oxidized when the tungsten wire is generating heat. Since the passing of electric current makes the conductor heat. When the temperature of tungsten wire rises, the length of radiated electromagnetic wave becomes short. At room temperature, tungsten wire can radiate ultrared rays. When the temperature rises to a certain degree, tungsten wire begins to radiate visible light, so tungsten wire begins to give out light.
Compared with tungsten wire, other metals would be burnt out before giving out light and also have certain risk. So tungsten wire is the best choice to make bulb.
