Tungsten disulfide (WS2) is a two-dimensional material that contains hexagonal crystal clusters. It is a solid lubricant powder, and is non-toxic and non-corrosive. As a dry lubricant, it can be applied to any surface, including plastics.

WS2 has excellent lubrication characteristics and is used as a solid lubricant for bearings and gears. In addition, tungsten disulfide also helps with reducing galling on bearings. WS2 has good anti-wear properties, and its low dynamic coefficient of friction can be used as an additive to lubricating grease.

WS2 is also used as a coating for metal components. Its high temperature resistance is great, ranging from -188°C to 2400°F. Moreover, it is very stable at high temperatures. This makes it an ideal lubricant for high-temperature applications. The material is also approved for food processing.

WS2 has also been used for aerospace missions. NASA engineers developed this material to help mechanical components run smoothly in space flights. Because of the extreme temperatures, lubrication would be challenging. But thanks to its high chemical stability, tungsten disulfide is the ideal dry lubricant for space missions.

Tungsten disulfide can be used in conjunction with other dry lubricants, such as silicone, petrochemical, and hydraulic fluids. Besides, it is very effective in reducing galling on bearings and improving performance of conventional lubricants.

WS2 can be used in many applications, including aircraft components, medical devices, and industrial components. Moreover, the dry lubricant can improve efficiency in fabrication. WS2 also helps to hold lubricants in place.
