Grain Boundary Engineering
At Urban Mining Company, Grain Boundary Engineering™ increases overall performance of the NdFeB product through control of chemical properties. Grain Boundary Modification™ is a new grain boundary engineering technique that allows for the systematic improvement of material properties including distribution and corrosion resistance.
Grain Boundary Modification
  • Reduces Dy content in the NdFeB product
  • Augments coercivity (iHc) up to 83%
  • Increases the temperature resistance of the magnet
  • Precisely controls drop in remanence (Br)
  • Improves reversible coefficient behavior (α, β)
  • Removes the limitation of thickness when compared to diffusion techniques
  • Used in both virgin and recycled production
