Compared to traditional radiation shielding materials, tungsten alloys provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material! Unlike lead, you’ll also reduce administration costs by eliminating the need to obtain special licensing—it’s not required.

Tungsten alloy is ideal for shielding against X-rays and gamma radiation. The very high density of tungsten 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 shielding characteristics.

Whether you need to protect sensitive electronic equipment or delicate human tissue, the energy-absorbing properties of Chinatungsten's tungsten alloys make them exceptional choices for radiation shielding applications, in both medical and industrial settings.

Clients all across the globe are taking advantage of tungsten alloy’s reliable radiation shielding properties. If you need to protect yourself, your patients or your equipment from the harmful effects of excess radiation, come to us!

Our products are available as finished machined parts or as short rod, round bar, and rectangular blocks.

SiliconCarbide is the only chemical compound of carbon and silicon. It wasoriginally produced by a high temperature electro-chemical reaction ofsand and carbon. Silicon carbide is an excellent abrasive and has beenproduced and made into grinding wheels and other abrasive products forover one hundred years.

Today the material has been developed into ahigh quality technical grade ceramic with very good mechanicalproperties. It is used in abrasives, refractories, ceramics, andnumerous high-performance applications. The material can also be madean electrical conductor and has applications in resistance heating,flame igniters and electronic components. Structural and wearapplications are constantly developing.

while foams of silicon carbide can be used very advantageously as a temperature-resistant and corrosionresistant insulating material and filter material or catalyst support. Pipes, crucibles, bricks or the like of these mixtures are suitable for use as high temperature materials because of their good chemical resistance.

Silicon carbide continuous filaments can be manufactured in accordance with a known process by exposing a carbon filament, manufactured according to conventional processes, to a silicon tetrachloride gas atmosphere at 800 1,200C (U.S. Pat. No. 3,433,725). According to a further known process, silicon carbide continuous filaments are obtained by coating a thin tungsten filament with silicon carbide, which is formed on the tungsten surface, kept at 1,200 to 1,300C, by pyrolysis of methyldichlorosilane (F. Galasso, et al., Appl. Phys. Lett. 9 (1966) 37). The disadvantage of these processes is that relatively thick silicon carbide fibers result which are difficult to handle, and their high manufacturing cost prevents a broad application.

Shaped articles such as, for example, pipes, crucibles or bricks can be manufactured according to known processes by sintering pulverulent silicon carbide, with addition of silicon powder, in appropriate molds, in most cases with the use of high pressures and temperatures, in the presence of nitrogen. In these cases, the silicon nitride formed acts as a sintering aid.

It is furthermore known to manufacture silicon carbide coatings on suitable shaped articles by pyrolysis of a mixture of slicon tetrachloride, toluene and hydrogen (K. Moers, Z. anorg. allg. Chem. 198 (1931) 243).

Foams of silicon carbide can be manufactured according to the process of U.S. Pat. No. 3,100,688, by reacting a mixture of finely divided silicon dust and carbon dust with dilute hydrofluoroic acid and heating the foam thereby formed, after drying, to a temperature of between l,400 and 2,200C under an inert gas.

Black SiC is a man made mineral with a high thermal conductivity rating of 100 W/m-K. It is extremely hard, around a Mohs 9.1 or 2550 Knoop. It has high strength at elevated temperatures. For example, at 1000oC, SiC is 7.5 times stronger than Al203 (aluminum oxide). Black SiC will contain some free silicon and carbon and thus is not as pure as green SiC. Black will range in purity from 97-99% pure, depending on grit size. Green SiC is made from Silica sand and coke, and is extremely pure. Hexagonally shaped, it breaks into very sharp particles. Our green SiC is 99.5% pure, exceeding JIS, ISO, & FEPA standards.

Green SiC is harder than black, coming in at a 9.4 Mohs and 2600 on the Knoop scale. Green is often the media of choice when it comes wire sawing. The micronization process of manufacturing our green SiC is controlled by a computer. Then the material is water classified/separated - this produces a very tight particle size distribution, as well as a reduction in fines, as preferred for accurate wire sawing applications. Unless your application requires an extremely pure SiC, by default, black is preferred due to its more economic pricing.

Compared to traditional radiation shielding materials, tungsten alloys provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material! Unlike lead, you’ll also reduce administration costs by eliminating the need to obtain special licensing—it’s not required.

Experts find that radiation exposure could be reduced by maxing shielding. The density of a material is related to its radiation stopping ability. Higher density means better stopping power and shielding. Due to a higher density, tungsten alloy has a much higher stopping power than lead. It is greater linear attenuation of gamma radiations means that less is required for equal shielding. Alternatively equal amounts of tungsten alloy shielding provide diminished exposure risks than equivalent lead shielding.

Tungsten alloy is a suitable raw 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), simplified life cycle and high strength. It 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 alloy is more acceptable in this case, for they are non-toxic.

Tungsten alloy is used in many radiation-shielding applications including industrial, nuclear and medical.

Tungsten alloy is used in many radiation-shielding applications including industrial, nuclear and medical. Because of its high density and high atomic number, is an effective construction material for shielding against gamma rays and x-rays. Lead and boron carbide can shield radiation too, but cannot perform as well as tungsten alloy.

Tungsten alloy is a suitable raw material for tungsten alloy radiation container, because of tungsten alloy radiation container combination of radiographic density (more than 60% denser than lead), good machinability, good corrosion resistance, high radiation absorption (superior to lead), simplified life cycle and high strength. Tungsten alloy radiation shielding can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Moreover, compared with lead or depleted uranium, tungsten alloy is more acceptable in this case, for it is non-toxic and environmentally friendly material.

Why we need tungsten alloy radiation shielding?

As medical science developing so repaid, there is more and more radiation in our life, which has become a new trouble, such as 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 other people safe from harmful effects of ionizing radiation, such as breast cancer, skin cancer, etc. One type of excellent radiation-absorbing medium is badly needed.
