Tungsten wire, a thin wire made by forging and drawing tungsten bars. Tungsten wire is mainly used in electric light sources such as incandescent lamps and tungsten halogen lamps. Our Tungsten wire is high quality made with more than 99.95% W. Tungsten has a very high melting point which makes this ideal for high temperature applications such as heating elements, incandescent lighting or hot wire cutting.
When working with tungsten wire, please take care as it a hard metal so can snap or shatter when being cut.
Applications:
Tungsten wires can be used for producing electric light source parts and electric vacuum components, heating elements and refractory parts in high temperature furnaces, heating elements used in vacuum metalizing or plating.
Tungsten wire has a resistivity of 5.3 * 10 ^ -8. Tungsten has a high melting point, large resistivity, good strength, and low vapor pressure. It is the best material for making incandescent filaments among all pure metals. However, tungsten is hard and brittle and difficult to process. When the current is heated to a certain temperature through the tungsten wire, the resistance value of the tungsten wire also increases to a certain value (the resistance value of the metal wire generally increases with the increase in temperature). At room temperature, the resistance of this object should be 1370 ℃ -2000 ℃, but this resistance value will change when the cross-sectional area length of the tungsten wire changes.
