Tungsten Disulfide (WS2) is one of the most lubricious substances in the world! It possesses good tribological properties, including a state of near-zero friction or superlubricity, and is thermally more stable and resistant to oxidation.

Tungsten Disulfide (WS2) is one of the most lubricious substances in the world! This dry/solid lubricant powder offers unmatched dry lubricity (COF: 0.03), outperforming even Graphite and Molybdenum Disulfide (MoS2).

WS2 is perfect for high temperature and high-pressure applications, with temperature resistance ranging from -450ºF (-270ºC) to 1200ºF (650ºC) in normal atmosphere, and from -305ºF (-188ºC) to 2400ºF (1316ºC) in vacuum. Its coated film can handle loads up to 300,000 psi.
