Tungsten Alloy Rod in Radiotherapy Equipment

Tungsten alloy rod is tungsten heavy alloy material used in radiation collimation, shielding, and protection structures of radiotherapy equipment. Radiotherapy systems require precise control of high-energy X-rays or gamma rays (γ-rays). Collimation and shielding structures define the radiation field, improve target positioning accuracy, and reduce the radiation dose received by non-target areas. Therefore, related materials need to provide high density, strong radiation attenuation capability, dimensional stability, and good machinability. CTIA’s tungsten alloy rod, featuring tungsten’s high atomic number, high density, and enhanced mechanical properties after alloying, serves as an important material for precision shielding and collimation components in radiotherapy equipment.

1. Characteristics of CTIA’s Tungsten Alloy Rod in Radiotherapy Equipment
(1) Excellent Radiation Attenuation Performance
High density and high atomic number provide strong attenuation of X-rays and γ-rays, enabling efficient radiation shielding in limited space.
(2) High Density for Compact Design
Density of 16.5-18.8 g/cm³ reduces the volume of shielding components, suitable for space-constrained designs.
(3) Good Dimensional Stability
High strength and low thermal expansion coefficient maintain stable dimensions during long-term operation and precision adjustment, meeting the accuracy requirements of radiotherapy equipment.
(4) Excellent Machinability
Better toughness and processability than pure tungsten, allowing machining into complex collimators and shielding assemblies via turning, grinding, wire cutting, and other processes.

2. Applications of CTIA’s Tungsten Alloy Rod in Radiotherapy Equipment
(1) Radiation Collimation Components
Used to manufacture collimator rods, beam-limiting components, and local radiation control parts to adjust the radiation beam range and reduce radiation exposure to non-target areas.
(2) Local Radiation Shielding Components
Used to manufacture shielding inserts, protective rods, and customized shielding structures to improve localized radiation protection performance.
(3) Internal Equipment Protection Components
Used in local shielding structures of radiotherapy equipment, such as linear accelerators and gamma knife systems, to reduce the impact of scattered radiation.
(4) Precision Mechanical Adjustment Components
Used in internal counterweights, positioning components, and adjustment mechanisms. The high density, high strength, and dimensional stability improve equipment operating stability.
