With rapid development of medical science, more and more radiation instruments are used in our lives. Medical instruments and nuclear power stations have become widespread and are now affecting all our lives. It is essential that people paid more attention to radiation and even more important for the institutions to protect public from the radiation exposure and to make sure to protect every radiation source of X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc.
In order to protect patients and personnel from harmful effects of ionizing radiation, such as breast cancer, skin cancer, etc an excellent radiation-absorbing medium is badly needed. Tungsten alloy housing shielding is the material to be used for radiation shielding.
Tungsten alloy is ideal for tungsten alloy housing shielding against X-rays and gamma radiation. The very high density of tungsten alloy housing shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the tungsten alloy radiation shielding characteristics.

Tungsten heater filament is made of tungsten wire, featuring high melting point and high corrosion resistance, mainly application in vacuum metalized applicant, such as aluminizing scope, aluminum spraying, chrome scope, mirror making, ceramic coating, plastics and heater element for decoration articles.
Tungsten heater filament can be stranded into single or multi wires according to the samples or drawings of customers. Pure wire and doped wire are both available. Diameter of tungsten wire: 0.2-1.2mm.
Tungsten heater filament, single or multiple strand tungsten, molybdenum, or tantalum wire. Stranded wire can incorporate a core of aluminum for wetting purposes.

Tungsten contacts are used in high voltage applications, usually where highly repetitive switching is required. Tungsten has a melting temperature of 3,380℃ which gives it excellent arc-erosion resistance.
Tungsten contacts may develop troublesome oxide films, especially when used as the anode contact in some DC applications. Therefore, tungsten contacts are often used as the cathode contact, and a palladium alloy used as the anode contact. Such a combination also minimizes contact interface resistance and material transfer.

As a special and effective boat vessel, tungsten boats are widely used in metallizing, electron-beam spraying as well as the heat process with sintering and annealing in vacuum coating industries.
Tungsten boats sources are used for the vacuum evaporation of materials that are in granular or pellet form. They can also be used to evaporate small lengths of wire or to evaporate materials which would not properly "wet" the surface of an evaporation filament. These boats are ideal for use in small evaporation systems, such as bell jars, for experimental and prototype work.

Tungsten ball is the general term for pure tungsten ball, tungsten alloy ball and tungsten carbide ball.
Pure tungsten ball is used the material of pure tungsten whose density is over 19.2g/cm3, and it is the highest density among tungsten balls. Another reason for applicator using pure tungsten ball is that tungsten ball has the highest melting point.
Tungsten alloy ball is tungsten ball alloy with Ni and Fe, or other metal element to improve other properties of tungsten, such as to make unbrittle and easy to be processed. Tungsten alloy ball can be marked words on the ball, but pure tungsten ball has no such properties.
