Preface
Research Background and Importance of Tungsten Alloy Collimator
Tungsten alloy collimators stems from the growing demand for radiation protection and precision beam control. In 2025, with the rapid development of global nuclear energy, medical imaging, aerospace and industrial detection technology, radiation safety and equipment performance optimization have become core issues in the industry. Tungsten alloy collimators stand out with their high density (17.0–18.5 g/cm³), excellent radiation shielding efficiency (gamma ray attenuation coefficient>0.15 cm ⁻ ¹ ) and mechanical strength (tensile strength>1000 MPa), becoming an ideal substitute for traditional lead -based materials . According to the 2024 International Atomic Energy Agency (IAEA) report, the global radiation protection market will grow at an annual rate of 12%, of which the demand for tungsten alloy collimators is expected to increase from 8% in 2023 to 15% in 2025, reflecting its importance in high-precision applications.
tungsten alloy collimators began in the mid-20th century. They were initially used for beam control in the nuclear industry and then expanded to X-ray and CT equipment in the medical field. In 2023, a pilot project at a nuclear power plant showed that the shielding efficiency of a 5 mm thick tungsten alloy collimator under a Co-60 source (1.25 MeV) reached 97%, which was 2% higher than that of a lead plate, and the weight was reduced by 20% (8 kg vs. 10 kg), significantly reducing the cost of facility maintenance. In 2024, the aerospace field further verified its value. A launch vehicle used a tungsten alloy collimator as a radiation shielding layer and successfully passed the 10 g acceleration vibration test with a strength retention rate of >95%. These cases highlight the reliability and versatility of tungsten alloy collimators in extreme environments.
At present, the global distribution of tungsten resources is concentrated in China (65% of reserves), Canada and Russia. The fluctuation of tungsten prices in 2025 (>320 US dollars/ton) has promoted the development of alloy formulation optimization and recycling technology. Enterprises such as CTIA GROUP LTD have improved the uniformity and shielding performance of collimators through nanotechnology (<50 nm particles). According to a medical equipment project in 2024, the proton beam (10 MeV) shielding rate of nano-enhanced tungsten alloy collimators reached 99%, and the weight was reduced by 15% (from 20 kg to 17 kg). However , high costs (>2,500 US dollars/ton) and processing complexity are still bottlenecks for promotion, which urgently need to be solved by technological innovation and large-scale production. These challenges and opportunities together constitute the background of tungsten alloy collimator research , prompting this encyclopedia to systematically explore its performance, applications and future potential.
Tungsten Alloy Collimator Encyclopedia Compilation Objectives and Structure Overview
The purpose of the Encyclopedia of Tungsten Alloy Collimators is to provide a comprehensive and authoritative reference resource for researchers, engineers and industry practitioners, filling the gap in the existing literature in the field of tungsten alloy collimators. As of July 1, 2025, there have been more than 500 patent applications related to tungsten alloy collimators worldwide , with an annual growth rate of 20%, but there is a lack of unified academic and industrial guidelines. This book is based on detailed technical data, case analysis and future forecasts, with the goal of:
- Technical Details : In-depth analysis of the material properties, manufacturing process and performance optimization of tungsten alloy collimators, covering the latest developments from powder metallurgy to 3D printing.
- Application expansion : Systematically organize its specific applications in the fields of medical, industrial, aerospace, etc., combined with actual cases in 2023-2025, such as nuclear power plant shielding and CT equipment upgrades.
- Forward-looking outlook : predicting market trends in 2030 and exploring the technical routes for smart collimators and sustainable production.
