Description
Tungsten Disulfide (WS₂) Micron Powder – 99.9% Purity, -325 Mesh
Product Overview
Tungsten Disulfide (WS₂) micron powder is a premium-grade solid lubricant engineered for extreme environments. With a high purity of 99.9% and fine particle size classified as -325 mesh, this powder delivers exceptional performance under high-temperature and high-pressure conditions. It is chemically inert, thermally stable, and provides ultra-low friction, even in dry or vacuum environments.
This material operates reliably across a wide thermal range — from -270°C to 650°C in atmospheric conditions and up to 1316°C in vacuum environments. Its excellent lubricating properties and strong load-bearing capacity make it a go-to solution for critical industrial, mechanical, and aerospace applications.
Applications
Tungsten Disulfide micron powder is widely used in high-performance coating and lubrication systems. When applied as a dry film or in composite lubricants, WS₂ significantly reduces friction, minimizes wear, and prolongs component lifespan. It is highly effective in:
-
Automotive industry: racing engines, valve train systems, pistons, precision gears
-
Aerospace components: bearings, shafts, actuators, turbine mechanisms
-
Cutting tools and machining: slitters, knives, molds, die surfaces, blades
-
Marine parts: chain drives, propeller mechanisms, corrosion-resistant assemblies
-
Industrial machinery: rotating equipment, high-speed bearings, robotics
-
Mold release agents and surface treatments for reducing friction and galling
Thanks to its low coefficient of friction (as low as 0.03) and excellent load-bearing capability, WS₂ is often used as a dry lubricant where oils and greases cannot perform, such as in vacuum systems or clean-room conditions.
