Tungsten wire has significant advantages as a material for glass heating, including but not limited to high melting point, thermal stability, electrothermal efficiency, mechanical strength and processing flexibility, so it is widely used in glass manufacturing, electron tube packaging and optical glass processing.

Tungsten wire for glass heating is a tungsten wire used for heating during glass processing or manufacturing. Tungsten has an extremely high melting point (about 3422°C) and good high temperature stability, and is an ideal heating element for high temperature environments. In the glass industry, tungsten wire is often used in precision equipment such as glass fiber drawing furnaces, glass tube production equipment or laboratory glass processing equipment.

Tungsten wire is often used in glass heating processes (such as glass melting, forming or annealing) due to its unique physical and chemical properties. Its main characteristics are as follows:

Like tungsten carbide powder (WC powder), ditungsten carbide is also a compound composed of the refractory metal tungsten and the non-metallic element carbon. Its English name is tungsten carbide, with the chemical formula W₂C, and it features a hexagonal close-packed (hcp) crystal structure. Due to slight differences in the crystal structures of WC powder and W₂C powder, their physical and chemical properties, as well as their applications, are also different. Note: The crystal structure of WC can be either a simple hexagonal lattice or a face-centered cubic lattice.
