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…
