Heavy rare earth elements (Dy, Tb) are applied to the magnet's surface and, through high-temperature diffusion, penetrate along the grain boundaries forming a high-coercivity layer — boosting thermal performance while reducing heavy rare earth consumption by 30% to 50% compared to conventional alloying.
Strip casting achieves precise control of the material composition. The molten alloy is rapidly cooled on a rotating wheel, forming thin strips that ensure a fine, uniform grain structure and stable properties in the finished magnet.
