Similar to tungsten-cobalt and tungsten-titanium-cobalt alloys, tungsten-titanium-tantalum (niobium)-cobalt alloys are widely used hard alloys. Due to their excellent physicochemical properties and strong versatility, they are also known as universal hard alloys or all-purpose hard alloys.

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:

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.
