Silicon carbide is composed of tetrahedra of carbon and silicon atomswith strong bonds in the crystal lattice. This produces a very hard andstrong material. Silicon carbide is not attacked by any acids oralkalis or molten salts up to 800°C. In air, SiC forms a protectivesilicon oxide coating at 1200°C and is able to be used up to 1600°C.The high thermal conductivity coupled with low thermal expansion andhigh strength give this material exceptional thermal shock resistantqualities.

Silicon carbide ceramics with little or no grain boundaryimpurities maintain their strength to very high temperatures,approaching 1600°C with no strength loss. Chemical purity, resistanceto chemical attack at temperature, and strength retention at hightemperatures has made this material very popular as wafer tray supportsand paddles in semiconductor furnaces. The electrical conduction of thematerial has lead to its use in resistance heating elements forelectric furnaces, and as a key component in thermistors (temperaturevariable resistors) and in varistors (voltage variable resistors).

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.

The tungsten alloy reliably shields against X-rays and gamma radiation. With its new production process and great expertise in the materials field, Chinatungsten has made the manufacture of shielding components particularly cost-effective.

Whether in the world of medical or industrial X-ray technology, radiotherapy or nuclear power stations: Wherever high-energy radiation is used, it is vital to protect people against it.

The denser the material, the better able it is to protect from radiation. That is why heavy elements absorb X-rays and gamma radiation particularly well. Lead is still the most frequently used shielding material. Because it is a very soft material, it is mostly used only in combination with support structures made of steel.

Lead is a toxic material that is harmful to the environment and humans. The onerous recycling process makes lead expensive despite the low initial procurement costs. Many enterprises are therefore looking for a suitable alternative for providing reliable radiation protection.

The density of tungsten is 60 percent higher than that of lead. That is why even thinner layers of tungsten are able to provide reliable shielding against radiation. The tungsten alloy DENSIMET® is particularly suitable as a shielding material. It consists of tungsten and a small proportion of nickel-iron. Like tungsten, the material has excellent shielding properties. However, it is also considerably more ductile than tungsten and can therefore be machined better.

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.
