The amorphous melt-spun ribbons of Nd-Fe-Co-Cu-Nb-B system alloys were prepared by single roller rapid-quenching method. The effects of composition, wheel velocity and heat-treatment on the magnetic properties were investigated. The amorphous Nd9Fe75.5Co8Cu0.5Nb1B6 ribbon prepared at a wheel velocity of 15.0m/s were crystallized by heat-treatment, and the optimum heat-treatment condition was found to be at 700°C for 5min, then the value of (BH)max was 114.8kJ/m3. The temperature coefficients of Jγ and HCJ for the ribbons crystallized from the amorphous Nd9Fe75.5Co8Cu0.5Nb1B6 alloy were α(Jγ)=-0.064%/°C (reversible) and β(HCJ)=-0.426%/°C (irreversible), respectively. The value of (BH)max for the compression molding Nd9Fe75.5Co8Cu0.5Nb1B6 isotropic bonded magnet prepared by using the ribbons annealed at 700°C for 5 min is 78.66kJ/m3 and the density is 6.23Mg/m3
