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.

Due to its excellent high-temperature resistance, mechanical strength, and chemical stability, black tungsten wire plays an irreplaceable role in lighting, electronics, high-temperature industries, welding, photovoltaics, medical treatment, and scientific research. The following details the main uses of black tungsten wire.

Due to its exceptional physical and chemical properties, black tungsten wire is widely used in lighting, electronics, photovoltaics, and high-temperature industries. As a processed product of the high-melting-point metal tungsten, tungsten wire possesses unique properties that enable it to perform exceptionally well in extreme environments. The following details its key characteristics.

Due to its unique chemical properties, black tungsten wire is widely used in high-temperature, vacuum, and specific chemical environments. As a high-melting-point transition metal, tungsten is extremely chemically stable, but it can also exhibit some reactivity under certain conditions. The following details the main chemical properties of black tungsten wire.
