The preparation technology and magnetic properties of Nd9.5Fe77B6Co5Zr2.5 nanocomposite magnets were investigated by melt spinning and crystallization process. The nonuniform composition and grain size can be induced by nanocomposite magnet prepared by arc-melt-spinning process, which will decrease the magnetic properties. These can be avoided by modification of preparing process. Induction-melt-spinning furnace was designed successfully and applied to prepare nanocomposite magnets. The bonded magnet with Br=0.736, Hcb=418 kA/m, Hcj=630 kA/m, Mr/Ms=0.7 and (BH)max=82.4 kJ/m3 was prepared by this technology.
