Product Description

High Performance Grain Boundary Diffusion Neodymium Magnets

 

1. What is Grain Boundary Diffusion (GBD) Technology?

In grain boundary diffusion (GBD) technology, the heat treatment temperature will be higher than the melting point of the Nd-rich phase, and then the Dy / Tb compound on the surface of the magnet can penetrate into the magnet through its grain boundaries.
