Jinci Haina New Material Technology (Nantong) Co., Ltd. recently completed a Series A+ financing round of tens of millions of yuan, led by Chengkai Fund with participation from Yueke Finance and follow-on investment from existing shareholder Hongfu Assets; Linglu Capital served as exclusive financial advisor. The funds will be directed toward construction of a nanocrystalline magnetic powder core production line, product R&D iteration and market expansion, accelerating large-scale volume production of high-end soft magnetic alloy powder cores. Founded in 2018, the company focuses on amorphous/nanocrystalline ribbons, magnetic cores and soft magnetic alloy powder cores, and has established an alloy powder core production base in Tongling, Anhui. Jinci Haina has built a complete product matrix covering amorphous magnetic powder cores, amorphous composite magnetic powder cores, nanocrystalline magnetic powder cores and nanocrystalline composite magnetic powder cores. Compared with conventional FeSi and FeSiAl products, its magnetic powder cores deliver 20% higher saturation resistance and more than 60% lower high-frequency loss; in the high-frequency band above 30 MHz, the permeability of its nanocrystalline materials can reach up to 12 times that of conventional MnZn ferrites, with 3 times the current handling capability. On the process side, the company's self-developed alloy formulation achieves trace-element proportioning precision of one part in ten thousand, roughly 10 times the industry level, enabling customized formulation development within 3 days; its proprietary composite-modified nano insulating coating technology uses a coating system combining inorganic and organic materials to improve high-temperature resistance and mechanical strength. In September 2025 the company published a patent for an "ultra-small laminated-thickness magnetic core forming device and forming method"; it has been granted 12 invention patents and 8 utility model patents. A magnetic powder core production line with annual capacity in the thousands of tons is under accelerated construction, and ultra-thin nanocrystalline cut magnetic cores have completed validation in a leading server power supply manufacturer's next-generation high-power-density AI server BRM power supply project and entered small-batch delivery. For the metal powder industry, this development signals a shift in soft magnetic powder cores from FeSi and FeSiAl systems toward amorphous/nanocrystalline systems, with high-power-density scenarios such as AI data centers, new energy vehicles and photovoltaic energy storage creating large-scale demand for high-frequency, low-loss powders. Jinci Haina's entry into the supply chains of leading customers such as Sunlord Electronics, Sungrow, Huawei and Sigenergy means that the batch delivery capability of nanocrystalline magnetic powder cores is beginning to undergo device-level verification, and process requirements for upstream atomization powder production, insulating coating and heat treatment will rise accordingly. Value for powder buyers: (1) Monitor the volume ramp of amorphous/nanocrystalline magnetic powder cores in AI server power supplies and new energy applications, and assess ahead of time the feasibility of replacing conventional FeSi powder cores; (2) when evaluating suppliers, focus on verifying insulating coating processes and formulation customization response speed, as these two factors directly determine high-frequency loss and batch-to-batch consistency; (3) incorporate the construction progress of the thousand-ton-scale production line into supply assurance assessments, and reserve alternative powder sources before large-scale capacity comes online.
