Zhongke Sanhuan Achieves New Magnet Performance Records, Advancing Tech for Miniaturization and Power Density

Published: Sep 8, 2026 14:46

【SMM Rare Earth Flash】 Following its March 2026 breakthrough in developing the world's highest comprehensive-performance ultra-high remanence sintered NdFeB magnets, Zhongke Sanhuan (000970.SZ) has achieved another technological advancement through its subsidiary Tianjin Sanhuan Lexi New Materials Co., Ltd. Two new magnet grades, tested by the National Institute of Metrology, China, have set new performance records: Model A achieved a room-temperature remanence (Br) of 15.407kGs and a maximum energy product (BH)max of 57.52MGOe, with further improvements in Br and (BH)max; Model B achieved an intrinsic coercivity (HcJ) of 20.86kOe and a (BH)max of 57.05MGOe, with simultaneous gains in coercivity and energy product.

This breakthrough will provide stronger technical support for the miniaturization, lightweighting, and power density upgrades of permanent magnet devices in precision sensing, intelligent robotics, low-altitude flight systems, and specialty motors. The company remains committed to advancing R&D in high-performance rare earth permanent magnets and accelerating the commercialization of technological achievements.

EU Launches €8.9M CIRCUIT4EU Project to Recycle Critical Raw Materials from E-Waste
【SMM Rare Earth Flash】 The EU has launched the CIRCUIT4EU critical raw materials recycling project under its Horizon Europe innovation program. The project has a total budget of €8.9 million, bringing together 21 partner organizations from 9 countries over a three-and-a-half-year period running until November 2029. The project focuses on recovering critical raw materials from printed circuit boards, permanent magnets, and electronic components in waste electrical and electronic equipment, targeting 9 of the 34 critical raw materials on the EU list, including copper, cobalt, nickel, antimony, tantalum, boron, and rare earth elements. Pilot applications will be conducted on four product groups: laptops, WiFi devices, e-scooters, and dishwashers. The initiative aims to support the EU Critical Raw Materials Act's 2030 benchmark of obtaining 25% of annual consumption from recycling sources, transforming e-waste into secondary raw material sources and strengthening the EU's domestic circular supply chain.
