Although tungsten alloy underwater assault rifle bullet looks like a nail, it can make the underwater rifle have a longer range and higher penetration than the fishing gun. Under water, the resistance encountered by the warhead "flying" is completely different from the air resistance it encounters when flying in the air, so whether the bullet is shot into the water from the air or underwater, bullets consume a lot of kinetic energy due to water resistance and water pressure, resulting in a sharp reduction in range.

Tungsten alloy underwater automatic rifle bullet having high aspect ratio is a kind of special bullet for using underwater. You know, the underwater automatic rifle is an underwater weapon specially developed for fighting frogmen, and has always been a field highly valued by various countries. As an important killing component of underwater rifles, the research and development of bullets is of great importance.

Tungsten alloy bullet has advantages of strong penetrating power, high hit rate and good toughness as the warhead of the bullet is made of high-quality tungsten alloy that has characteristics of high density, high strength, high hardness, small thermal conductivity, small thermal expansion coefficient, and good mechanical processing performance, oxidation resistance and corrosion resistance. Tungsten alloy can be processed into large-diameter or small-diameter warheads.

Tungsten alloy bullet is one of the most important bullet for applications of underwater submachine gun. And such bullets are also called tungsten alloy underwater submachine gun bullets - a type of arrow-shaped projectile made of tungsten heavy alloy. And it is the special tungsten alloy long rod warhead that make the submachine gun have a longer effective range. Also, it guarantees the stability of the bullet when flying underwater, while ensuring the hit rate and reliable lethality.

Tungsten disulfide nanosheets are an important functional material. It is reported that WS2 nanosheets are a graphene-like two-dimensional layered nanomaterial with unique physical and chemical properties, so that it is widely used in lubricants, lithium-ion batteries, supercapacitors, semiconductor electronic devices, hydrogen storage and other fields.

Tungsten disulfide grease is a new type of grease made of a new lubricating material - tungsten disulfide (WS2) and other materials. It is WS2 that make this grease have high temperature resistance, excellent oxidation stability, good abrasion resistance at extreme pressure, good resistance to water washout, and long service life. Also, such a WS2 grease provides excellent anti-rust and anti-corrosion protection to prevent the corrosion of metals by water, steam and acids.

As its name suggests, tungsten disulfide high temperature extreme pressure grease is fabricated using tungsten disulfide (WS2) particles as a lubricating material and can be applied at high temperatures and extreme pressures. Such a lubricating grease has characteristics of good stability, adhesion, wear resistance, oxidation resistance, and high temperature lubrication performance at extreme pressures. Also, it has a long service life in the range of ultra-high and ultra-low temperature. Lubrication temperature range is from -20 °C to 250 °C, up to 300 °C in short-term. The applicable temperature ranges of anti-seize is -60 °C to 800 °C.

Tungsten disulfide high temperature grease is uniform and smooth grease (black) that has excellent water resistance, mechanical shearing, adhesion, anti-corrosion and anti-rust performance. And such a grease does not sinter at high temperature, so there is no stuck phenomenon on bearing. This is because this kind of grease uses tungsten disulfide (WS2) - a new lubricating material having the best lubricating performance as an additive.

Tungsten disulfide can be used as a lubricant, a catalyst, and so on, so that it has a wide application. As a lubricant, WS2 is suitable for lubrication under high temperature, high pressure, high speed, high load and high vacuum conditions, and its lubrication performance is better than that of molybdenum disulfide (MoS2). WS2 can be used alone, or added to engineering plastics to make self-lubricating components, or mixed with volatile solvents to spray on metal surfaces, for applications in punching and forging to extend the life of molds and improve product finish.

As a new solid lubricating material, tungsten disulfide (WS2) is more heat-resistant, wear-resistant, environmentally friendly, energy-saving, and cost-saving than traditional solid lubricants.
