Tungsten Alloy Rod in Medical Radiation Shielding

Tungsten alloy rod in medical radiation shielding is high density tungsten alloy rod used for manufacturing radiation protection and shielding components in medical radiological equipment. Based on tungsten (W) with nickel (Ni), iron (Fe), or copper (Cu) as binder phases, it is manufactured through powder metallurgy processes. CTIA’s tungsten alloy rod features high density, excellent radiation shielding performance, high strength, and dimensional stability, providing efficient radiation protection within limited spaces. The material can be processed into medical linear accelerator collimators, rotary shielding components, radioactive source shielding components, and other radiation protection structures, and is widely applied in radiation shielding systems for radiotherapy equipment and nuclear medicine devices.

1. Characteristics of CTIA’s Tungsten Alloy Rod in Medical Radiation Shielding
(1) High-Efficiency Radiation Shielding Performance
With a density of 16.5–18.5 g/cm³, the material provides excellent attenuation capability against X-rays and gamma rays, achieving higher shielding efficiency at the same thickness and enabling compact radiation protection designs for medical equipment.
(2) Environmental Safety
Contains no lead, avoiding contamination risks associated with traditional lead shielding materials and meeting modern medical equipment requirements for environmental protection and safety.
(3) Structural Stability
Maintains stable dimensions under temperature variations and long-term operating conditions due to its high strength and low coefficient of thermal expansion, ensuring reliable shielding performance over extended service periods.
(4) Precision Machining Capability
Supports turning, milling, grinding, and Electrical Discharge Machining (EDM) processes to produce collimators, shielding blocks, and customized radiation protection structures with complex geometries.
(5) Adaptability to Special Environments
Offers W-Ni-Cu (non-magnetic) grades suitable for strong magnetic field environments such as Magnetic Resonance Imaging (MRI) systems, while providing good corrosion resistance for long-term medical equipment operation.
