Product Description

Thanks to the tungsten alloy's unique physical features of higher density than lead, the material tungsten alloy can
be processed as a lead replacement for shielding against X-rays and gamma radiation.  It allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics and protect sensitive electronic equipment or delicate human tissue, the energy-absorbing properties of Kefeng tungsten alloys make them exceptional choices for radiation shielding applications, in both medical and industrial settings.
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.
Our products are available as finished machining parts or as short rod, round bar, rectangular blocks and other shapes per your requirements and drawings.


 
Characteristics and features

As medical science developing, 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.
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. With a higher density, tungsten alloy has a greater protection 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.

1. Can be machined to different shapes per customer drawings and requirements. 
2. Good corrosion resistance
3. High radiation absorption (superior to lead)
4. Simplified life cycle and high strength.
5.  Non-toxic material as a replacement to lead
