P. Granberg et al., MAGNETIC-PROPERTIES OF ND-FE-B MAGNETS PREPARED BY EXTRUSION AND SINTERING TECHNIQUES, Journal of magnetism and magnetic materials, 144, 1995, pp. 1067-1068
Nd-Fe-B permanent magnets have been manufactured by extrusion of gas a
tomized powder of the nominal composition Nd16Fe78B6. The magnetic pro
perties are found to be anisotropic. The energy product, intrinsic coe
rcive field strength and the remanent flux density measured perpendicu
lar to the extrusion direction are 90 kJ/m(3), 880 kA/m and 0.72 T res
pectively.
