WS2 - Tungsten Disulfide

Tungsten Disulfide (WS2) is a dry/solid lubricant powder and is one of the most lubricious substances in world. WS2 offers excellent 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. It offers temperature resistance from -450 deg F (-270º C) to 1200 deg F (650º C) in normal atmosphere and from -305 deg F (-188º C) to 2400º F (1316º C) in Vacuum. Load bearing ability of coated film is extremely high at 300,000 psi.

Tungsten Disulfide (WS2) can also be used instaed of Molybdenum Disulfide (MoS2). See comparison of WS2 / MoS2.

Since the powder offers one of the lowest Coefficient of Friction (Dynamic @ 0.03 & Static @ 0.07), the applications are unlimited and could be tried with every conceivable idea.
