Tungsten Disulfide Powder

Email us

Tungsten Disulfide Powder (WS2 powder) is dry/solid lubricant powder and is one of the most lubricious substance in world. WS₂ offers excellent dry lubricity (COF: 0.03) unmatched to any other substance, including graphite or molybdenum disulfide (MoS₂).
Tungsten Disulfide Powder can also be used in high temperature and high-pressure applications. It offers temperature resistance from -270 ° C to 650° C in normal atmosphere and from -188° C to 1316° C in Vacuum. Load bearing ability of coated film is extremely high at 300ksi. WS2 powder is a new lubricating material with excellent lubrication performance. The grease added WS2 powder has good performance, such as high dropping point, high oil film strength (PB), and low friction coefficient. It can also be applied to anti-friction material in carbon brush industry, super rigidity material and weld thread), used in aviation, military, etc.
