磁体材料迭代推动产业升级

Core Insights - The fusion industry is entering an accelerated phase driven by policy support and capital expenditure, with major countries expected to introduce fusion policies by 2025, marking a shift from laboratory research to industrial layout and regulatory framework construction [2] - Low-temperature superconductors are relatively mature, while high-temperature superconductors are expected to become the mainstream in the future, with magnetic materials being the core foundation for stable magnetic field confinement in fusion devices [2] Industry Overview - The magnet system is a core cost component of fusion projects, with the ITER project using low-temperature superconductors having 86% of its component costs attributed to parts, of which magnets account for 28% [3] - In high-temperature superconductor projects, the cost of the magnet system increases further, with the ARC project showing that magnets account for 46% of the total cost [3] Market Potential - The market size for second-generation high-temperature superconducting tapes for global controllable fusion devices is projected to reach 300 million yuan in 2024, with an expected growth to 4.9 billion yuan by 2030, representing a compound annual growth rate of 59.3% from 2024 to 2030 [3] Investment Recommendations - The magnet segment, being the highest value component in the fusion system, is currently transitioning from low-temperature to high-temperature technology validation and evolution, indicating a positive outlook for demand driven by the capital expenditure cycle in fusion [3] - Key suppliers in the magnet segment include: 1) Low-temperature superconductors: Western Superconductor 2) High-temperature superconductors: Shanghai Superconductor (not listed, controlled by Jingda Co., Ltd. (600577)), Lianchuang Optoelectronics (600363), Eastern Superconductor (not listed, a subsidiary of Yongding Co., Ltd. (600105)) 3) Core suppliers of tantalum and niobium: Dongfang Tantalum Industry (000962) [3]
