Injection molded Sm-Fe-N anisotropic magnets using unsaturated polyester resin

摘要

New injection molding technology using unsaturated polyester resin and anisotropic Sm-Fe-N magnet powder is successfully developed. High temperature use is possible. The temperature of initial irreversible flux loss of -5% is 151 degree C at Pc = -2 with a sample of B_r=0.74T, H_(CJ)=840kA/m and (BH)_(max)=102kJ/m~3. To produce thin sheets is possible. B_r=0.72T,H_(CJ)=796kA/m and(BH)_(max)=94.7kJ/m~3 are obtained with a sheet of 50mm x 20mm x 0.36mm.
