The company has set independent R&D center--Engineering (Technical) Center. Now the company owns about 20research personnel, about 10 middle and high ranking personnel with technical posts.The company strengthens exchange relevant to technical cooperation with scientific research institutions, and has established long-term stable cooperative relationship with Ningbo Material, Technology and Engineering Research Institute of the Chinese Academy of Sciences, and other scientific and research units successively

Research and Development



On the basis of producing high quality raw blocks, NBZY has been Researching and developing updated surface protection technology vigorously. We can provide customers with high quality coatings and humidity resistance of coated magnets are quite good to assure magnets safe enough even in rigorous environments.During the process of coating and plating, NBZY attaches great importance to environment protection, all coatings meet the requirements of ROHS.



Through the persistent research on component formula and process technology, the micro-structure of magnet has been optimized and the particle size also been largely minimized. All achievements mentioned above make NBZY's magnet much less reliable to the heavy rare earth material and, therefore, greatly reduced the magnet cost.  For now, most of NBZY's grades are free of or with much less heavy rare earth.

Weight Loss

Under the environment of high temperature, high pressure and high humidity, the weight loss level of uncoated magnets can qualitatively reflect life clearly . Referring to the standard IEC68-2-66 and after 20days HAST testing, weight of loss than 2mg/cm2 is available for NBZY magnets, which is the top level worldwide.
