NdFeB magnet strength is a defining performance metric that positions neodymium iron boron magnets as the most powerful permanent magnets in widespread industrial use. Their exceptional strength originates from the intrinsic properties of the Nd₂Fe₁₄B crystalline phase, which exhibits high saturation magnetization and strong magnetocrystalline anisotropy. These atomic-level characteristics enable the generation of intense and stable magnetic fields within compact material volumes. From an engineering perspective, NdFeB magnet strength is quantitatively described through parameters such as remanence, intrinsic coercivity, and maximum energy product. High remanence determines the achievable magnetic flux density, while intrinsic coercivity reflects resistance to demagnetization under external magnetic fields or elevated temperatures. The maximum energy product represents the usable magnetic energy per unit volume and serves as a critical indicator for system miniaturization and efficiency optimization. Manufacturing processes play a central role in realizing and controlling NdFeB magnet strength. Advanced powder metallurgy techniques allow precise alignment of magnetic domains during compaction, establishing anisotropic structures that significantly enhance magnetic output. Subsequent vacuum sintering and heat treatment optimize grain boundary phases and reduce magnetic defects, directly contributing to improved coercivity and long-term stability.
