Introduction:
You can find that tungsten is at work whenever the heat’s on. Tungsten wire having the highest melting point, good electric conductivity, excellent thermal conductivity and a uniquely low thermal expansion and a very high level of dimensional stability. Tungsten can suitable for very high-temperature applications.
Aceon supplies W wire and other tungsten alloy wire (such as tantalum tungsten alloy wire, and other tungsten alloy wire). W wire has the same properties of tungsten materials. The crystal structure of tungsten wire is compact.
Applications:
Tungsten wire is usually used to manufacture electric light and electric vacuum components and the high temperature heating body and high temperature structural parts( like filament for all kinds of lamps) and is applied to make vacuum evaporation plating tungsten spiral

Appearance:
Tungsten wire is coated with colloidal graphite on the surface and tungsten appears uniform black. W wire appears metal luster if being removed colloidal graphite.
Tungsten wire supply:
We supply pure W wire, tantalum tungsten alloy wire, and other tungsten alloy wire. Our W 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? Aceon will explain how W 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 W wire, the electric resistance of W wire rises and gives out heat, then W wire and tungsten alloy wire give out light. At the same time, the melting point of W 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 W 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 W wire rises, the length of radiated electromagnetic wave becomes short. At room temperature, W wire can radiate ultrared rays. When the temperature rises to a certain degree, W wire begins to radiate visible light, so W wire begins to give out light.
Compared with W wire, other metals would be burnt out before giving out light and also have certain risk. So W wire is the best choice to make bulb.
We can also supply molybdenum wire, HTM(High-Temperature Molybdenum Wire) and other wire with high density and excellent quality.
