Tungsten Disulfide Dry Film Lubricant

Exceptionally Slick, Uniquely Thin. Remarkably Durable

WS2 Slide Show

Originally developed for hard vacuum of space, Tungsten Disulfide's exceptional lubricity virtually eliminates friction: the source of heat and torque. Less friction prevents galling, cold welding and seizure in bearings, gears, pistons, threads and Fastener. A uniquely thin coating (about 20 millionths of an inch) WS2 can coat the tiniest parts without affecting dimensions or performance.

Primary Uses of Tungsten Disulfide


Designed To Be Impinged

Applied Tungstenite specializes in AMS 2530 the most recent specification for impinged tungsten disulfide. High velocity impingement forms a strong molecular bond to the substrate resulting in the longest wear life of any other solid lubricant.

    News: NASA Spotlights Applied Tungstenite

    Spinoff Magazine "Dry Film Lubricant Smoothes the Way for Space Travel, Industry"

    Applied Tungstenite has been featured in NASA's Spinoff Magazine. "Most of the power, communications, imaging, and computing technology on the Mariner planetary space probes—cutting-edge at the time—is now the NASA equivalent of stone tools. However, one technology, a dry lubricant that was developed for the later Mariner missions in the late 1960s and early '70s, is still essential to modern spacecraft."

    "Current SAE specifications for aerospace materials still include the stipulation that the lubricant be applied using the impinging process,"

    "tungsten disulfide offers the precision that aerospace engineers need, and because Applied Tungstenite is the only company currently certified in applying it by the original method,"
