How Does the Diameter of Tungsten Wire Affect Applications? 183

The diameter of tungsten wire is very important in some cases. The metal wire is a common wire material commonly used in light bulbs, electronic devices, thermocouples, heaters, and more. Its diameter determines its physical properties such as resistance value, current capacity, and service life, so the diameter has an important impact on application performance. Here are some situations where W wire diameter needs to be considered: Bulb: the sizes of the tungsten filament are important factors in determining the…

Black Tungsten Wire Is Used in Electronics, Aerospace, and Medical Fields 160

Black tungsten wire is a type of tungsten wire that has been coated with a black oxide to enhance its corrosion resistance and provide a sleek, black appearance. Tungsten is a dense, metallic element with a high melting point, making it an ideal material for high-temperature applications, such as heating elements and electrical conductors. In the production of this wire, the tungsten is first cleaned and then heated in an oxygen-rich atmosphere, causing a black oxide layer to form on…
