About Ningbo Nailiyu Magnetics

Technology drives development; innovation secures the future. Ningbo Nailiyu Magnetics Technology Co., Ltd. (formerly Ningbo Hengshen Magnetic Industry Technology Co., Ltd.), founded in 2011 in 3, is located in Ningbo, Zhejiang Province, China. As a national high-tech enterprise integrating R&D, production, and sales of rare-earth permanent magnet materials, we specialize in providing high-performance core magnetic materials for the new energy and energy-saving environmental protection industries.

The company is certified under ISO9001, IATF16949, and ISO14001 management systems. We possess full-scale manufacturing capabilities covering R&D, blank production, finished part processing, surface treatment, performance testing, and magnetic component assembly. Our high-performance sintered NdFeB permanent magnets feature high magnetic strength, high coercivity, excellent thermal stability with resistance to demagnetization, and long service life. They are widely used in automotive parts, industrial motors, energy-efficient elevators, home appliances, industrial robots, low-altitude aircraft, wind power generation, and rail transit—key sectors in environmental protection and intelligent manufacturing.

Driven by a relentless commitment to innovation, our R&D team continuously advances in materials science and process optimization. We master critical technologies such as grain boundary engineering and green, high-efficiency surface protection, while leveraging core capabilities in dual-alloy fabrication and grain boundary diffusion. This has enabled a strategic technological upgrade—from reducing heavy rare earth usage to systemic innovation—positioning us at the forefront of the rare-earth permanent magnet industry. We have secured multiple invention patents and utility model patents.

The lab features industry-leading testing equipment, including laser particle size analyzers, magnetic moment testers, universal mechanical testing machines, salt spray test chambers, and NdFeB magnetic property analyzers. We precisely control key process quality, trace product characteristics, and comprehensively validate magnetic performance, mechanical properties, and corrosion resistance to provide authoritative, reliable data for R&D and finished products. Our team of senior testing technicians undergoes regular skills training, ensuring seamless integration of equipment and personnel to guarantee high performance, consistency, and long-term quality stability.

Ningbo Nailiyu Magnetics Technology is part of the Jinhui Permanent Magnet Group. Guided by our core values of "Customer First, Technological Innovation, and Synergistic Development," we focus on green new energy and energy-saving environmental protection. We provide reliable magnetic material solutions to customers worldwide and are committed to becoming a trusted global supplier of magnetic materials and components.
