Tungsten Alloy 20CC Syringe Shield

Why Do We Need Tungsten Alloy Radiation Shielding?
With rapid development of medical science, more and more radiation instruments 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 no doubt the best solution. Excellent radiation-absorption, twice the density of lead and good physical resistance is main reasons to use tungsten alloy radiation shielding.

Product Description

Advantage of Tungsten Alloy Radiation Shielding

Experts find that radiation exposure could be reduced by maxing shielding. The density of Tungsten Alloy Radiation Shielding material is related to its radiation stopping 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.

Zhuzhou Jiuding Metal Technology Co., Ltd could design and make special size based on different properties:




HA170 is the most ductile and readily machinable grade. Common application areas include counterbalancing weights for the aviation and aerospace industries, crankshaft and auto racing car, bucking bars for rivet setting, and radiation shielding.


HA175 is commonly used to produce chatter-resistant boring bars and tool shanks as well as radiation shielding components.


HA180 is often applied where size is a factor in the placement of balance or ballast weights. It should be typically of parts with small volume but heavy density. Other applications include radiation shields and collimators of x-ray or gamma ray beams.


The densest of the Ni-Fe binder alloys with tungsten, and is the preferred grade for radiation shielding in the medical imaging industry.


Adding copper as a substitute for iron in the binder phase, as there is requirement for nonmagnetic working environment and ideal choice for nonmagnetic radiation shielding.


Much denser than HA170C, can be used in large scale shielding in nonmagnetic working environment.



We own international advanced technology of Metal Injection Molding (MIM) and pressing technology, we can manufacture standard products and various non-elevation products.
