The Difference Between Black Tungsten Wire and Cleaned Tungsten Wire

tungsten wire image

The main difference between black tungsten wire and cleaned tungsten wire lies in surface treatment and appearance: black tungsten wire has a gray-black color due to the presence of graphite emulsion on its surface; cleaned tungsten wire is black tungsten wire that has been alkaline washed or electrolytically polished, resulting in a silvery-white surface with a smooth finish, making it suitable for high-precision and high-temperature environments. Each type has its own advantages depending on the application requirements.
