Terbium in permanent magnets
Terbium can enhance coercivity in certain high-performance NdFeB systems. Its presence must be substantiated for the specific material or batch.
Role in the magnet
Understand terbium’s role in the material system
A specific proportion cannot be inferred from appearance, application or magnet grade.
Function
Terbium can enhance coercivity in certain high-performance NdFeB systems. Its presence must be substantiated for the specific material or batch.
Material boundary
Application, magnet shape and grade code are no substitute for composition data or suitable analysis.
Evidence
Batch documentation, manufacturer data or suitable analysis must relate to the specific lot.
Weight
Total magnet mass, assembly mass and the mass of the individual element are different quantities.
Purchase assessment
Form, origin, condition, net magnet mass and potential recovery route are assessed first.
