Tungsten alloy radiation shielding part has the advantages of high density, high hardness, and strong radiation absorption ability, so that it can effectively shield medical radiation sources such as X rays and gamma rays. The overall performance of tungsten alloy radiation shielding parts is much better than lead radiation shielding parts. Also, the radiation shielding part made of tungsten heavy alloy is non-toxic and environmentally friendly. So, tungsten alloy is widely applied in hospital nuclear medicine department, nuclear medicine laboratory, disease prevention center, biological laboratory, etc.

Tungsten alloy shielding pot is a container that is specially designed for storing and transporting medical radionuclide preparations. The shielding function of the tungsten alloy shielding pot is much better than the traditional lead shielding pot. Due to its high density, the volume of tungsten alloy is 1/3 smaller than lead, but shielding function is equivalent. So, tungsten alloy shielding pot is more popular than lead shielding pot.

Tungsten alloy radioactive source container is a new type of radiation shielding container that is made of environmentally friendly and non-toxic high density alloy - tungsten heavy alloy. Tungsten alloy radioactive source container that has better radiation shielding effect than lead container can be used to store and transport medical radioactive sources such as cobalt-60, cesium-137, iridium-192, iodine-131, iodine-125 and technetium-99m.

Tungsten alloy radioactive source shield may be a tungsten alloy container for storing and transporting medical radioactive sources, or may be a shield used for medical equipment containing radioactive sources (such as bone densitometer, gamma camera, gamma knife, cobalt 60 treatment machine, etc.) to prevent a large amount of radioactive energy exposure, reduce radioactive pollution, and improve safety. Tungsten alloy radioactive source shields can provide a more reliable and environmentally friendly radiation shielding effect than traditional lead shields.

Tungsten alloy shield is widely applied in medical equipment for diagnosis or treat. Tungsten alloy shield may be some tungsten alloy leaves on radiotherapy equipment such as electronic linear accelerators. It has been reported that tungsten alloys are outstanding materials for shielding of gamma rays and X rays as tungsten alloys have multifarious properties such as high radiation absorption, good corrosion resistance, high ductility, high durability, high density, good adaptability, high machinability, low toxicity and high strength. Therefore, tungsten alloy shields are often used to replace lead shields.

WO3 is the optimal sensing material for producing O3 gas sensor by detecting changes in surface conductance after tungsten trioxide film on sensor contacts the measured gas - O3. As we all know, O3 has been widely used in disinfection and sterilization, sewage treatment and other aspects.

WO3, a n-type oxide semiconductor, is regarded as the best sensing material for fabrication of H2S gas sensor to realize the monitoring and detection of H2S gas. You know, H2S gas is an air pollutant, which not only seriously threatens human health, but also affects industrial production. In industry, the maximum allowable mass concentration of H2S in air is 0.01 mg/L. So, there is an urgent need to develop a H2S gas component.

WO3 thin film is regarded as the best sensing material for the fabrication of sensitive and selective NO2 gas sensor. Some experts have fabricated NO2 gas sensor using WO3 thin films grown directly on to a soda-lime glass substrate without assistance of any seed layer by a simple and a facile hydrothermal technique.

WO3 has excellent sensitivity and fast response speed to NH3 - colorless gas with strong pungent odor, so it is often made into a semiconducting gas sensor for NH3 detection. And therefore, WO3-based NH3 gas sensor has become one of the key research projects of scholars at home and abroad.

Solid tungsten carbide drill has the characteristics of high efficiency, high accuracy, high degree of finish, high hardness, high strength, high wear resistance, bending resistance, breakage resistance, and long service life. And such a drill is easy to use, safe, reliable, economical and labor-saving. So, the tungsten carbide drill can reduce the processing cost of each hole while ensuring the drilling quality and drilling rate of the hole.
