Preface
Tungsten Alloy Shielding Industry Background and Importance
Tungsten alloy shielding plays an indispensable role in modern science and technology and industry. In 2025, with the rapid development of nuclear energy, medical imaging, aerospace and defense industries, the demand for high-efficiency and lightweight radiation shielding materials will increase significantly. According to the 2024 report of the International Tungsten Association (ITA), the global tungsten alloy shielding market has reached US$600 million, with an annual growth rate of 12%, and is expected to grow to US$1.2 billion in 2030. Tungsten alloy has become an ideal substitute for traditional lead shielding materials due to its high density (17.0–18.5 g/cm³), excellent radiation attenuation coefficient (0.15–0.20 cm ⁻ ¹ ) and good mechanical properties, especially in the context of increasingly stringent environmental protection and health and safety requirements.
tungsten alloy shielding is reflected in its wide range of application scenarios. In 2024, the medical field (such as CT equipment and radiotherapy equipment) accounts for more than 50% of the market demand (about 300 tons), the demand for industrial nuclear waste treatment increases by 10% (2023 data), and the demand in the aerospace field (such as deep space probes) increases to 30% in 2025. In addition, in 2023, China took the lead in formulating the draft GB/T 26011 (Tungsten Alloy Shielding Processing Specification), marking the acceleration of industry standardization. In 2025, the draft was submitted to ISO and is expected to be globally unified in 2030. This series of developments highlights the strategic position of tungsten alloy shielding in technological progress and industrial upgrading.
Tungsten Alloy Shielding Parts Writing Purpose and Target Readers
The purpose of this book, Encyclopedia of Tungsten Alloy Shielding, is to provide a comprehensive and authoritative reference that systematically summarizes the technical characteristics, manufacturing processes, application areas and future trends of tungsten alloy shielding. In 2025, facing the rapidly changing market and technological challenges, industry practitioners, researchers and policymakers are in urgent need of an integrated knowledge platform. Through detailed data analysis and case studies, this book aims to fill the gaps in existing literature in standardization, application optimization and sustainable manufacturing.
The target readers include: (1) material scientists and engineers who are concerned about the design and performance optimization of tungsten alloy shielding parts; (2) technicians in the medical, industrial and aerospace fields who need to understand specific application scenarios; (3) policy makers and business managers who are concerned about market trends and supply chain management; (4) students and academic researchers who seek theoretical foundations and experimental data. In 2024, an international seminar (IAEA Radiation Symposium) pointed out that 80% of the participants believed that comprehensive guidelines were essential for the development of the industry. This book responds to this demand.
Research methods and data sources of tungsten alloy shielding
The research method of this book combines literature review, experimental data analysis and industry research. In 2023, the author team collected more than 1,000 academic papers from ScienceDirect, IEEE Xplore and CNKI. In 2024, through field visits to leading companies such as CTIA GROUP LTD, more than 500 hours of production data were obtained. In 2025, Monte Carlo simulation (MCNP) software was used to verify radiation shielding performance, with an error control of less than 1%.
Data sources include: (1) standard documents from the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM); (2) the 2024 market report from the International Tungsten Association (ITA); (3) more than 200 tungsten alloy shielding patents included in the China National Knowledge Infrastructure (CNKI); and (4) CTIA GROUP LTD White Paper from 2023 to 2025. All data have been cross-verified on the eve of July 3, 2025 to ensure authenticity and reliability.
