Tungsten Disulfide (WS2) Powder - Lower Friction

Tungsten Disulfide (WS2) is dry/solid lubricant powder and is one of the most lubricious substance in world. WS2 offers excellant dry lubricity (COF: 0.03) unmatched to any other substance, including Graphite or Molybdenum Disulfide (MoS2). Tungsten Disulfide (WS2) can also be used in high temperature and high pressure applications.

Tungsten Disulfide - an overview | ScienceDirect Topics

Tungsten disulfide (WS 2) is a solid lubricant with a lamellar structure similar to that of MoS 2.However, it has not been so widely studied according to the research literature. Since it possesses a crystal structure similar to that of MoS 2, it is expected to exhibit similar tribological properties including a state of near zero friction or superlubricity.
