NdFeB magnets were born in the 1980s. In 1982, researchers from Sumitomo Special Metals in Japan and General Motors in the United States independently developed NdFeB magnets. Sumitomo focused on sintered NdFeB, while GM pioneered bonded NdFeB technology. Subsequently, technical patents were mainly concentrated in the hands of Japanese companies. During the early commercialization stage in the late 1980s and early 1990s, Japanese manufacturers dominated the global NdFeB market.
Since 1990, driven by rare earth resource advantages, the loosening of patent barriers, and technological diffusion, China began to enter the high-end NdFeB market and established large-scale production. After 2005, Chinese enterprises rapidly expanded their scale, and China became the world’s largest magnet producer.
By around 2015, China’s magnet production had exceeded 80% of the global total. Subsequently, with the development of the new energy industry, the demand for NdFeB grew rapidly, and Chinese enterprises began to enter the high-end market. European and American companies continue to maintain a presence in the high-end market, with a production capacity share of about 5-8%, while Japan accounts for about 5-10%.
As EV demand continues to grow, Europe and the United States are attempting to build local magnet supply chains. Rare earth supply security has become a strategic issue, and the rankings and market shares of global magnet companies have been constantly changing and will continue to evolve in the future.

Top China Manufacturer – Core Competitiveness of China’s Magnetic Material Industry
China’s ability to capture over 80% of global production capacity is not merely due to resource endowments, but to the “full-chain ecological closed-loop” it has built over decades:
Rare Earth Mining and Refining Advantages
China controls the majority of global rare earth processing and separation capabilities. Beyond mining, the critical factor is the deep processing capability to convert ore into high-purity oxides and alloys. The cost advantage derived from this scale effect is hard for other countries to match in the short term.
Cluster Effects and Industrial Ecosystem
Magnetic material clusters like Ningbo, Baotou, and Ganzhou provide a “one-stop” manufacturing environment—ranging from mold making and equipment to surface treatment—drastically shortening development cycles.
Technological Evolution and Application Innovation
The large-scale application of technologies like “grain boundary infiltration” has promoted the industry’s transition toward green and sustainable manufacturing.
High Market Responsiveness
Deep integration with the domestic new energy vehicle supply chain allows for rapid R&D iteration and a closed-loop cycle from product development to customer validation.
Conclusion
There is no single “optimal choice” in the global magnet supply chain; there are only partners that best match your product R&D and delivery requirements.
For applications involving high entry barriers and extreme environments—such as aerospace, national defense, deep-sea exploration, and medical implants—the priority should be top-tier international manufacturers, as they offer extreme product stability, customized magnetic circuit integration, and full-lifecycle technical support.
For clients focused on precision engineering and high-performance motors, regional leaders are often the ideal choice; these suppliers typically possess deep patent portfolios and highly mature process control capabilities, ensuring patent compliance, exceptional product consistency, and precision machining and assembly services.
Finally, for companies in a rapid growth phase that demand strict cost control, supply chain resilience, and fast delivery, the priority should be high-cost-performance magnet manufacturers, as they can provide the most competitive pricing alongside the most agile customized responses.
