WS2 Powder as a solid lubricant has remarkable characteristics in terms of physical properties. WS2 Powder is most commonly used as a lubricant in petroleum-based oils and greases. Among solid lubricants, the coefficient of friction of WS2 Powder tends to decrease with increasing load. WS2 Powder is also lubricious at high temperatures of 450°C, helping to prevent sintering or seizing.
Grease added with WS2 Powder has excellent high temperature resistance, wear resistance, good adhesion, water resistance, oxidation resistance and mechanical stability. After adding WS2 Powder, the working limit high temperature of ultra-high temperature grease reaches 800℃, and the working limit low temperature of low temperature grease reaches -60℃.
WS2 Powder is a solid lubricant grade available in two grades- High-purity ultra-fine and High-purity coarse particles.Typical WS2 content (calculated average) is 99.9%.

FIG.1 WS2 Powder special grease.
Gray-black grease refined with WS2 Powder solid lubricant, anti-oxidation, anti-corrosion and other additives. This WS2 Powder grease can be used to lubricate friction parts and bearings operating under extremely high temperature, heavy load, humidity, pollution and other harsh working conditions, and can provide maximum anti-wear and anti-rust and anti-corrosion protection. It can be applied to low temperature of -30℃, and the maximum intermittent temperature resistance can reach 800℃.
FIG.2 Packaging of WS2 Powder.
WS2 Powder is packed in iron drums, 25 kg per drum.
On January 30, 2023, molybdenum price rose by more than 20% in a single day, breaking a new 17-year high. Molybdenum is known as the "war metal", "steel warrior". Molybdenum is valued by more and more countries. China is the world's richest country in molybdenum resources, with reserves of 4.3 million tons, followed by the United States (2.7 million tons) and Chile (1.8 million tons), which acco...more
