Kefeng's Tungsten Heavy Alloys precision parts are widely used in medical science because of their exceptional radiation management capacity. We provide state-of-the-art components such as shafts, stationary and rotating anodes, bar materials, screws and for X-ray tubes, anti-scatter grids and multi-leaf collimators. As to dynamically manipulate beam shape and deliver accurate focus during radiation therapy. Tungsten alloys are also utilized for shields and beam collimators. Our experience with extensive precision machining enables us to produce ultra-thin tungsten plates with exceptional flatness and surface finish. These plates are a key component of the detector plate assemblies used in CT scanners.
In terms of the nuclear medicine field, significant danger to human life can result from radioactive leaks. To ensure personnel safety, imaging applications require optimum radiation shielding. We develop advanced tungsten alloys for radiation shielding technologies in nuclear medicine and molecular imaging. The x-ray and gamma radiation absorption efficiency of tungsten alloys is 50% higher than conventional lead due to the high density of tungsten alloys.
These dense tungsten alloys attenuate specific wavelengths of electromagnetic radiation, which enable it to deliver extremely safe therapeutic and diagnostic treatments. Typical radiation shielding applications include components for brachytherapy, syringe covers for radioactive isotope injections, isotope source containers for transporting radioactive materials to cancer treatment hospitals. Tungsten-based alloyed materials are also used in gamma camera collimators and SEPTA plates as anti-scatter grids in PET scanners.

Characteristics And Features
The heavy tungsten alloy material possess the highest melting point of all metals and suitable for extremely high-temperature environment. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability. Kefeng's high-density balance weights are compact products ideal for applications where space is at a premium. Based on tungsten heavy alloys (WHA) with densities over 60% higher than lead, our balance weights empower manufacturers with small-form ballast for maximum weight in the smallest space.
