Tungsten carbide graver is also known as cemented carbide graver, which has higher hardness, better wear resistance and longer service life than the commonly used carbon steel graver and white steel graver. Wherein, carbon steel graver is generally suitable for beginners as it has low hardness and strength.

Tungsten carbide glass cutter is a tool used for cutting or scoring glass such as LCD optical glass, quartz glass, and crystal glass. There is a small wheel of tungsten carbide materials. Such a glass cutter has the characteristics of high hardness, good wear resistance, straight scribing, no edge collapse and long service life.

Tungsten carbide cutting wheel is mainly composed of a WC hard phase and a Co bonding phase, which is suitable for cutting brittle materials such as ceramic tiles, glass, glazed tiles, polished tiles, etc.

Tungsten carbide scriber is a fitter tool that is mainly applied for scribing on the surface of different workpieces such as steel plates, and ceramic tiles. The scriber made of high quality tungsten carbide is often used in conjunction with guide tools including steel rulers and scribing templates, etc.

Tungsten disulfide is a new type of graphene-like two-dimensional material, which has great application potential in electrical devices, energy, biology and composite materials.

How to prepare tungsten disulfide nanoparticles? At present, the flower-shaped WS2 nanoparticles are mainly prepared by hydrothermal method. While this method has the disadvantage of low yield, which is not conducive to mass production. So, some experts have proposed a simple process - high temperature vulcanization method - to prepare flower-shaped WS2 nano particles. The high purity WS2 nano particles are prepared by this method with low cost and high yield, so it is expected to be used in large-scale industrial production.

Tungsten disulfide catalyst has excellent dispersibility and catalytic activity in both polar and non-polar catalytic reaction systems. Some experts formulate the tungsten source, sulfur source, reducing agent, ionic liquid and deionized water into the initial reaction mixture in a certain order and method, and then crystallize it under hydrothermal conditions in a sealed high-pressure reactor. After filtering, washing and drying the crystallized product, a tungsten disulfide catalyst is obtained.

Tungsten disulfide lubricant, which is made from solid tungsten disulfide (WS2), lubricating oil and other components, has a wide temperature range, excellent anti-extreme pressure performance, anti-corrosion performance, anti-radiation performance and other comprehensive performances, so that it can fully meet the demanding use requirements, such as high temperature, vacuum environment and large load. Also, such a lubricant can be used to lubricate various mechanical equipment in corrosive environments where requiring increasing load and decreasing friction coefficient.

Tungsten alloy underwater bullet is a specially designed tungsten alloy bullet with large aspect ratio and excellent performance for applications of underwater rifles and underwater submachine guns. It means that the warhead of the tungsten alloy bullet for underwater firearms is slender, and therefore its effective range is far from that of ordinary bullets. Tungsten alloy warhead of such a bullet looks like a needle.

Tungsten alloy core armor-piercing bullet is a new type of armor-piercing projectile developed to replace the depleted uranium projectile. Compared with toxic and radioactive depleted uranium shells, tungsten alloy core armor-piercing projectiles is an environmentally friendly weapon. Moreover, the armor-piercing projectile using tungsten alloy as the core material has the advantages of high speed, large kinetic energy, low trajectory, short flight time, high hit accuracy, and large armor-piercing power. In a word, the overall performance of tungsten alloy projectiles is not worse than that of depleted uranium projectiles.
