Tungsten Disulfide Powder (WS2 Powder)

Product Information

Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.

Tungsten Disulfide Powder (WS2 Powder) is a dry/solid lubricant powder and is one of the most lubricious substances in the world. WS2 offers excellent dry lubricity unmatched by any other substance, including Graphite or Molybdenum Disulfide (MoS2). 

Tungsten Disulfide (WS2) is dry/solid lubricant powder and is one of the most lubricious substances in the 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 Powder (WS2 Powder) Features

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 a normal atmosphere and from -305 deg F (-188º C) to 2400º F (1316º C) in Vacuum. The load-bearing ability of coated film is extremely high at 300,000 psi.

Tungsten Disulfide (WS2) can also be used instead of Molybdenum Disulfide (MoS2). 

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

Applications of Tungsten Disulfide Powder (WS2 Powder)

1) Mixing the WS2 powder with wet lubricants (such as oil, grease & other synthetic lubricants):
The powder can be mixed 1wt% to 15wt% (as required) with grease or oil. This will enhance the lubricity of the mixture and also improves the High Temperature and Extreme Pressure properties of the mixture. During the use, WS2 in the mixture will get coated on mating/moving parts, which in turn reduces friction and improves lubricity and the load-bearing ability for much longer cycles.

2) Coating the WS2 powder on a substrate requiring (dry) lubricity:
The powder can be coated by spraying (at 120 psi) the substrate with dry (& cool) pneumatic air. It does not require any binders and spraying can be done at normal room temperature. The coated film will be 0.5 microns thick. In an alternative application method, the powder can also be mixed with Isopropyl alcohol and this paste could be buffed to the substrate. The coating applications are already established in many areas such as Automotive parts, Racing Car Engine and other parts, Aerospace parts, Bearings (Linear, Ball, Roller, etc), Shafts, Marine parts, Cutting Tools, Blades, Slitters, Knives, Mold release, Precision Gears, Valve components, Pistons, Chains, Machinery components, and many other areas.
