Tungsten Alloy X-ray Target

Tungsten alloy X-ray target can be subjected to higher loadings than stationary anodes. By rotation of dish-shaped X-ray targets under the electron beam, a new, already cooled part of the target surface is continually used as the focal spot. Moreover, tungsten alloy X-ray target cools down more rapidly by radiating its heat. Far more energy per unit time can therefore be supplied to a tube with an X-ray target in comparison with a stationary anode.

Guangxi Chentian Metal Product Co. Ltd  can supply the whole range of Mo alloys and tungsten X-ray targets. Tungsten alloy X-ray targets that are optimally suitable for individual customer requirements, such as mammography Mo X-ray targets and tungsten X-ray targets, which are used from the general medical diagnostic and amigo- cardiograph to computer tomography.

Advantage of Tungsten Alloy Radiation Shielding

Experts find that radiation exposure could be reduced by maxing shielding.The density of a material is related to its radiation protection ability. Higher density means better stopping and absorbing radiation ray . Due to a higher density than most other materials, tungsten radiation shielding has a much higher ability of absorbing and stopping almost rays than others metals such as the traditional radiation shielding – lead. Tungsten radiation shielding greater linear attenuation of gamma radiations means that less is required for equal shielding. Alternatively equal amounts of tungsten shielding provide diminished exposure risks than equivalent lead.

Tungsten heavy alloy is the right material for radiation protection, as its combination of radiographic density (more than 60% denser than lead), machinability, good corrosion resistance, high radiation absorption (superior to lead and steel), simplified life cycle and high strength. Tungsten radiation shielding can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Besides, compared with lead or depleted uranium (DU),tungsten radiation shielding is more friendship for the environments both lead and DU for it is no any toxic.

Why Do We Need Tungsten Alloy Radiation Shielding?

With rapid development of medical science, more and more tungsten radiation shieldings are used in our lives. Medical instruments x-ray 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, doctors, nurses and other people who may be exposed to radiation, sources of the radiation must be safely separated and shielded. It is crucial that holding and delivery instruments for radioactive materials would keep the radiation levels low enough, not to create harmful effects of ionizing radiation such as breast cancer, skin cancer, etc. Lead and steel are the traditional protection materials, but tungsten alloy radiation shielding is without a doubt the best solution. Excellent radiation-absorption and radiation shielding, twice the density of lead and good physical resistance are main reasons to use tungsten alloy radiation shielding.

Tungsten Alloy Radiation Shields


Tungsten alloys are not only very dense, but they are also very good at attenuating ionising radiation. This makes them ideal for shielding applications such as in nuclear medicine in the nuclear industry.

The ability to attenuate radiation is often expressed in “tenth layer thickness” – the thickness of a plate required to reduce the transmitted radiation to one tenth of the intensity of the incident radiation; the lower the figure, the better the shielding. The attenuation properties also vary with the incident energy if the radiation.

Graph 1 – Comparative Absorption Data as a Function of Energy

Comparative Absorption Data
Within the tungsten alloy range, the tungsten content varies from 90% to 97% by weight. More tungsten improves the radiation attenuation and so reduces the tenth layer thickness. this is illustrated in Table 1 at a fixed incident γ ray energy (Co60), where the absorption data for two of the Guangxi Chentian Metal Product Co., Ltd. products and lead are compared. Also shown are the corresponding half thickness of shielding needed to halve the radiation intensity

Derby Tungsten Cylinders


Pinewood Derby Tungsten Alloy Cylinder can be used as counterweight in pinewood derby. Generally, pinewood derby contains five 1/2 ounce cylinders, one 1/4 ounce cylinders, and two 1/8 ounce cylinders. Using the incremental cylinders, you can adjust weight of pinewood derby tungsten alloy cylinder slightly.

For similar reasons tungsten is a superior product for weighting cars. Tungsten is 3.2 times the weight of the no-lead weighting material often used on cars, thus it enables tremendous flexibility in the design of the car. Coincidentally, tungsten has been used by NASCAR for the metal roll cage and as frame ballast to lower the center of gravity of the race car.

How to Use Derby Tungsten Cylinders?

Tungsten Cylinders can be easily used for car weighting by drilling one or more 25/64″ or larger diameter holes into the block and then inserting the desired number of cylinders. The hole can then be plugged with a piece of 3/8 inch dowel rod. Since the Tungsten Cylinders are very hard, do not plan to drill out any extra weight. Instead, use an alternate method to make fine adjustments such as adding/removing tungsten beads.

What Is Tungsten Alloy Tube?


Tungsten alloy tubes are usually consist of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy tube is contain Co、Mo、Cr, etc., The most important property for it is its small volume with high density, which means it could be used in some fields need the little but heavy parts, such as the counterweights of golf club, fishing weights, counterweights for military defense, such as counterweights for hunting gun, prefabricated fragments, the missile weapons, armor piercing ammunition; counterweights for oil logging; also some fields concerning with precision instrument, such as mobile phone vibrator, clock cube, self-winding watches, anti-vibration toll holders, flywheel weights, etc.

As tungsten heavy alloy is high density with small capacity, high temperature resistance, reduction in press down-time, minimal extruded metal pick-up, high impact resistance and crack resistance, wonderful shock resistance, good corrosion resistance, etc. Therefore, tungsten alloy products are increasingly welcome by public. Tungsten alloy tubes can be used in various fields, and also can be machined into different size. We can provide all kinds of tube according to your requirements.

Tungsten alloy tube is a suitable raw material for radiation protection for its high density (more than 60% denser than lead), good mechanical strength, and low thermal expansion with good corrosion resistance, high radiation absorption (superior to lead), simplified life cycle and high tensile strength. Tungsten heavy alloy can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Besides, compared with lead or depleted uranium in the past, tungsten heavy alloy is more acceptable in this case, for tungsten alloy tubes are radiation-free and non-toxic.
