This paper deals with the magnetic and technological properties of isotropic Nd-Fe-B magnets over a wide range of Nd and B contents. They can be used to determine the optimum composition based on requirements. In anisotropic magnets, Nd and B ranges for production of high energy product rings was determined in Nd-Fe-Co-Ga-B system. This is also used in production.
