[SMM Rare Earth News Flash] Zhong Ke San Huan, a leading enterprise in rare earth permanent magnets, successfully developed ultra-high performance sintered NdFeB permanent magnets. According to authoritative detection by the National Institute of Metrology of China, the magnet achieved a remanence (Br) of 15.32 kGs at room temperature, an intrinsic coercivity (HcJ) of 17.89 kOe, and a BH max of 56.8 MGOe, making it the rare earth permanent magnet with the highest coercivity among all publicly reported ultra-high remanence magnet systems worldwide. The R&D team achieved a major breakthrough in the comprehensive performance of the magnet without excessive reliance on heavy rare earth elements such as dysprosium and terbium.
