Description
Tungsten Disulfide (WS₂) Micron Powder – 99.9% Purity, 1 µm
Tungsten Disulfide (WS₂) micron powder is a high-performance solid lubricant known for its exceptional thermal stability, low coefficient of friction, and chemical inertness. With a purity level of ≥99.91% and particle size distribution optimized for fine applications (D50 ~1.23 µm), this powder is ideal for demanding industrial environments. It performs reliably under extreme conditions — ranging from -270°C to 650°C in atmospheric environments, and up to 1316°C in vacuum — making it a versatile solution for lubrication and wear resistance across industries.
Applications
WS₂ micron powder is widely used in:
-
High-temperature and high-pressure systems
-
Dry film lubricants and anti-friction coatings
-
Automotive components (e.g., racing engine parts, valve trains, pistons)
-
Aerospace mechanisms (bearings, actuators, shafts)
-
Precision instruments (mold release agents, slitters, cutting tools)
-
Marine and industrial machinery
-
Gear systems, chains, knives, blades, and other moving parts
When applied as a coating, WS₂ forms a thin, uniform film that dramatically reduces friction, enhances load-bearing capacity, and extends component life in tribological systems. It is especially favored in clean or vacuum environments where traditional lubricants cannot be used.
