Grain Boundary Diffused (GBD) Neodymium magnets are the most powerful magnets currently available. They are the premium choice for maximum performance.
Grain Boundary Diffused magnets employ a secondary manufacturing process to concentrate the Heavy Rare Earth Element Dysprosium into the grain boundaries of the magnet microstructure, hence the name. This not only nets a performance increase but uses less Dysprosium making them more price stable than traditional method magnets.
All GBD Neodymium NdFeB is REACH and ROHS compliant and does not contain SVHC’s whilst licensed grades are produced to ISO9001 and ISO14001 Quality Control Standards. Certificates of Conformity, MSDS and PPAP’s can be supplied on request.
GBD Neodymium grades exist with the maximum recommended temperature ratings - from +60°C up to +230 °C but these ratings are GUIDELINE values only. The actual maximum temperature rating depends on the shape of the magnet and the design of the application. GBD magnets are limited in thickness to 8mm, and certain grades are not available with some magnet geometries.
Please contact us for the highest available grade in your magnet design.
