Tungsten disulfide (WS₂), a transition metal sulfide, typically appears as a gray-black powder. It exhibits excellent lubricating properties with a low friction coefficient and maintains stability under extreme conditions such as high temperature and pressure, making it commonly used as a solid lubricant. Additionally, it shows promising application potential in fields such as catalysis, energy storage, and semiconductors, positioning it as a highly regarded multifunctional inorganic material.

Halogen lamps are a specialized type of light source widely used in lighting, automotive, stage, and other applications. 

Due to its excellent high-temperature resistance, long lifespan, high luminous efficiency, and stability, halogen lamp tungsten wire is widely used across various fields. Whether in home lighting, automotive illumination, professional stage lighting, or industrial applications, it demonstrates unique advantages.

The production of halogen lamp tungsten wire is a complex and precise process, involving multiple steps such as tungsten powder preparation, tungsten rod forming, wire drawing, annealing, and surface treatment.
