Tungsten Disulfide WS2

Tungsten Disulfide (WS2) is one of the most lubricous materials known to science. With a Coefficient of Friction at 0.03, it offers unparalled dry lubricity compared to any other substance used in its applications. Because of its outstanding versatility, it can also be used in both high temperature and high pressure applications. It provides temperature resistance from -450 oF (-270oC) to 1200oF (650oC) in normal atmosphere and from -305oF (-188oC) to 2400oF (1316oC) in Vacuum.

WS2 versatility in product use is shown by its wide array of uses shown here.

Punches & dies, cutting tool, rollers,  seals shafts and spindles, sliding or rotating components, defense components, aerospace components, machinery components, extrusion dies, precision gears, power transmission components, as well of hundreds of other  application.
