As a common material, tungsten wire is widely used to make filaments and other high-temperature components, especially in light bulbs and electronic devices. The following are the advantages and disadvantages of tungsten wire:

Cleaned Tungsten Wire refers to a filament made of tungsten metal. It is widely used in various industrial and scientific fields because of its high melting point (about 3422°C), high strength and good conductivity. The surface of cleaned tungsten wire is generally treated with alkali washing, showing a silver-gray metallic luster, so it is called "white tungsten wire".

The main characteristics of tungsten wire are as follows:

High Melting Point: Tungsten has an extremely high melting point of about 3422°C, the highest of all metals, and is suitable for use in high temperature environments, such as incandescent bulbs and electron tubes.

Black tungsten wire is a filament made of tungsten metal. Usually, the surface is not polished or specially treated, and the graphite emulsion is attached, showing a dark gray or black appearance, hence the name "black tungsten wire". Tungsten is a high melting point (about 3422°C), high density, corrosion-resistant metal, and is widely used in many fields due to its excellent physical and chemical properties. Black tungsten wire is mainly made by powder metallurgy and wire drawing. Its surface may retain trace oxides due to oxidation or production process, so the color is darker.
