Founded in 1995 and headquartered in Baoji, Shaanxi — China’s "Titanium Valley" and the country’s largest base for rare-metal processing — Baoji Yunjie Metal Products Co., Ltd. has specialized for over three decades in refractory and specialty metals, including tungsten, molybdenum, tantalum, niobium, titanium, nickel, and zirconium. Today, Yunjie is recognized as a leading specialist and innovator in the region’s specialty-metal processing industry.
Yunjie operates a 15,000 m² manufacturing campus with 8,000 m² of integrated R&D, production, and office facilities, and a registered capital of RMB 15 million. The company has established comprehensive quality management, production assurance, and in-house R&D and innovation systems — providing end-to-end, hardware-to-process control that underpins stable quality and supports large-scale, high-precision manufacturing.
Focusing on special metals and alloys (W, Mo, Ti, Ta, Nb, Zr, Ni), Yunjie runs complete processing lines — including rolling (calendering), heat treatment, and sheet-metal & precision machining — enabling full in-house control from raw-material processing to finished-product delivery.
Nickel plates and sheets have become indispensable materials in the construction of fusion energy components, largely driven by their excellent high-temperature strength, corrosion resistance, and fabrication versatility. Fusion energy reactors operate under extreme conditions such as intense neutron irradiation, elevated temperatures over 600°C, and exposure to chemically aggressive coolants. Nickel alloys meet these demands by delivering both mechanical integrity and longevity.
Specifically, nickel-based plates and sheets are widely used in:
The high purity and specific alloying of nickel plates and sheets allow custom tailoring of material properties for fusion requirements, such as precipitation hardening or grain boundary optimization to impede radiation damage.
The fusion energy sector is rapidly advancing, with both public and private investments accelerating development of next-generation reactors such as tokamaks, stellarators, and compact fusion devices. This momentum fuels increasing demand for high-performance specialty metals like nickel.
Key market and technological trends include:
Beyond the traditional uses, nickel plates and sheets also play proactive roles in several cutting-edge fusion energy component applications:
Guided by the principle “Quality ensures survival, efficiency drives growth, and continuous improvement earns customer satisfaction,” Yunjie has continuously upgraded its quality systems for more than 30 years. With professional manufacturing services and consistently excellent product performance, we have earned the lasting trust of customers in China and around the world.
