It has been a project taking half a year to finish the structure, key words and content, and finally h5.chinatungsten.com is established.

As a typical representative of super hard materials, tungsten carbide is called "industrial teeth", and its excellent wear resistance is a high-quality embodiment of long-term use.

Toshiba Materials exhibited a lithium-ion battery that uses violet tungsten oxide as a negative electrode material and can achieve ultra-fast charging. This battery has applications ranging from automobiles, micro/light hybrid trains, elevators, uninterruptible power supply UPS to high current power supply. The application advantages are obvious and the coverage is wide.

Yellow tungsten oxide, more precisely, hexagonal tungsten trioxide (h-WO3), can be used to prepare a new gas sensor of high sensitivity and low power consumption. The prepared high-performance gas sensor has excellent sensitivity to toxic and harmful gases in the environment, such as CO, NOx, NH3, and H2S. Therefore, researchers have conducted extensive and in-depth research on various h-WO3 gas sensors.

Yellow tungsten oxide, or tungsten trioxide (WO3), can be used for flame retardant modification of wool fabric. Specifically, the researchers used WO3 sol instead of WO3 powder to flame retard the wool fabric.

Yellow tungsten oxide, or tungsten trioxide, is an important component in the preparation of new radiation-proof glove. According to the researchers, a new type of radiation protection material (It is lead-free to avoid lead hazard.) containing nano tungsten trioxide should be prepared at first. This new type of radiation protection material includes the following components by weight: nano tungsten trioxide: 3-10%; lanthanum trioxide: 3-10%; aluminum fluoride: 20-35%; nano bismuth trioxide: 55-73%; fullerol nanoparticles: 1-2%.

Tungsten alloy submarine counterweight is an important part of the counterweight cabin. It ensures that the weight of the submarine itself reaches a certain value, thereby realizing ups and downs. This is because tungsten alloy has high density, so the counterweights made using tungsten alloy as raw material are smaller in size than the weights made of other materials. Therefore, the weight distribution is easier to control and the sensitivity of the control mechanism is increased.

Tungsten alloy green bullet has higher density than lead bullet so that it has better penetrating power for armor piercing. And numerous countries have used tungsten alloy bullet for a number of years as it has high density and good firing properties, but without using lead.

Military tungsten alloy swaging rod made of 93% W-Ni-Fe has higher tensile strength than common tungsten alloy rod. Also, such a military swaging rod has many other good properties. So, it is mainly used to manufacture rifle bullets, sniper rifle bullets, and warheads of kinetic energy penetrator.

Tungsten alloy kinetic warhead has high hardness, high temperature resistance and good impact resistance, so it can destroy solid fortifications. Tungsten alloy kinetic warhead also has high density. It means that the mass of tungsten alloy warhead is very large in a unit volume. Small size, big powder. Therefore, the specific gravity of the warhead to the entire missile can be used to control the power distribution and kinetic energy maintenance of the missile.
