Superior Performance with Tungsten-Copper Composite X-Ray Anodes

HOSO produces high-qualitystationary anodes that are back-cast with copper from tungsten, potassium-doped tungsten (WVM), or tungsten-rhenium (WRe). HOSOCP®CBT - Back casting technology combination of tungsten and copper. This advanced joining technique ensures non-defect bonding between the two materials, providing the best thermal conductivity.

Introduction: The Core Component Powering Imaging Excellence​

The X-ray anode target stands as a critical determinant of system performance, image quality, and operational reliability in modern imaging technology. As the demand for higher power, greater resolution, and increased throughput intensifies, conventional pure tungsten anodes face significant thermal management challenges. Our solution—advanced tungsten-copper (W-Cu) composite anodes manufactured via a specialized back-infiltration process—overcomes this barrier through material science innovation, setting a new standard for next-generation X-ray systems.

​Core Technology: The Perfect Material Synergy​

Our stationary anodes are engineered using a unique manufacturing process: a high-melting-point, high-purity porous tungsten (or tungsten-rhenium alloy, potassium-doped tungsten) matrix is first created. Subsequently, high-thermal-conductivity copper is infiltrated into this matrix under high temperature and pressure. This results in an unparalleled metallurgical bond, creating a functionally graded material:

• ​The Role of Tungsten:​​ Serving as the electron bombardment layer, tungsten ensures efficient X-ray generation and exceptional focal spot stability due to its extremely high melting point and impressive X-ray yield.

• ​The Role of Copper:​​ Acting as the heat sink, copper's superior thermal conductivity rapidly dissipates the intense heat generated at the focal spot, effectively preventing target overheating and melting.

This optimal "front-office/back-office" design allows the tungsten layer to perform the "work" of X-ray generation while the copper layer manages "cooling," achieving the perfect balance of function and performance.

​Your Key Advantages: Why Choose Our W-Cu Anodes?​​

1. ​Exceptional Thermal Management​

   The high thermal conductivity of copper significantly reduces the operational temperature of the anode target face. This enables longer exposure times, higher tube currents, and shorter cooling cycles, thereby dramatically increasing equipment throughput.

2. ​Drastically Extended Service Life​

   Effective heat management fundamentally mitigates thermal stress and recrystallization-induced cracking or deformation of the target surface. This extends the service life of the anode assembly by multiples, reducing the total cost of ownership for your systems.

3. ​Higher Power Loading Capacity​

   The superior heat dissipation capability allows our anodes to withstand higher instantaneous and continuous power loads. This provides stable support for demanding applications such as computed tomography (CT) scanning and real-time industrial non-destructive testing (NDT).

4. ​Uncompromising Focal Spot Stability​

   The high melting point and low vapor pressure of the tungsten-based material ensure that the focal spot size and geometry remain stable under long-term, high-load operations, resulting in consistently sharp and high-quality images.

5. ​Customized Design and Manufacturing​

   We offer comprehensive customization services, including material selection (pure W, WRe, WVM), geometric configuration, cooling structure design, and integration with other components (e.g., rotors), to meet your specific application requirements.

​Primary Fields of Application​

Our tungsten-copper composite anodes are the ideal choice for a wide range of high-end applications:
