Zhong Ke San Huan Develops NdFeB Magnet with 57.52 MGOe Energy Product

Highlights

• Tianjin Sanhuan Lucky developed a sintered NdFeB magnet measured at 57.52 MGOe maximum energy product and 15.407 kGs remanence by China's National Institute of Metrology.
• A second magnet achieved 20.86 kOe coercivity, offering greater resistance to demagnetization for demanding motor and sensor applications.
• REEx classifies the result as an R&D performance milestone, not a confirmed commercial breakthrough, as no yield, cost, or mass-production data were disclosed.
• Zhong Ke San Huan is one of China's largest NdFeB producers with over 12,000 tonnes of annual magnet capacity, underscoring the scale behind its R&D efforts.
• The advance highlights that the West must compete against where China's rare-earth industry is heading, not just its current capabilities.
