Western Metal Materials Co.,Ltd. (002149.SZ) has seen its stock price accelerate sharply. On December 18 and 19, the company's shares hit consecutive daily limit-up gains. Since November, the stock has surged up to 123.33% from its low, reaching a historic market capitalization of 18.42 billion yuan.
On December 19, the A-share "controlled nuclear fusion" sector index surged 2.89%. Market sentiment was boosted by reports that a Trump-affiliated company plans to acquire a nuclear fusion startup. Trump Media & Technology Group has agreed to merge with TAE Technologies, a nuclear fusion energy firm, in an all-stock deal valued at over $6 billion. The transaction aims to combine Trump Media's capital access with TAE's fusion technology to support the booming AI industry. Following the news, Trump Media's stock soared 41.93% in a single session.
Controlled nuclear fusion, often called the "artificial sun" due to its similarity to solar energy production, is considered humanity's ultimate solution for clean, nearly limitless power. Recently, China and France deepened nuclear energy cooperation during French President Macron's visit. The two nations signed their 15th nuclear cooperation protocol, covering areas including fusion technology, nuclear fuel cycles, and waste management.
Western Metal Materials, headquartered in Shaanxi and majority-owned by the Northwest Institute for Nonferrous Metal Research, is a leader in China's high-end titanium products sector. Titanium products accounted for 69.83% of its H1 2025 revenue. The company also produces tungsten-molybdenum materials. According to Zhejiang Securities, its tungsten-copper thermal components are already used in nuclear fusion experimental devices, strengthening its competitive edge. Its subsidiary, Xinuo Xigui, is China's sole supplier of silver alloy control rods for nuclear reactors.
Beyond nuclear fusion, Western Metal Materials benefits from the "commercial aerospace" trend. Titanium, known as the "space metal," is critical for rockets and satellites due to its strength and heat resistance. The company's niobium alloys have supported major projects like the Long March rockets and China's space station.
However, financial pressures remain. The company reported a 19.59% YoY decline in 2024 net profit (158 million yuan) and a 49.76% drop for the first three quarters of 2025 (69.25 million yuan). Experts caution that commercial nuclear fusion remains distant—China's research, ongoing since the 1970s, is transitioning from physics to engineering, with commercialization projected between 2045-2050.
