More Information
Summary:The invention provides permanent magnetic steel for a magnetic latching relay and preparation method of the permanent magnetic steel. The permanent magnetic steel alloy comprises, by weight, 29-33 parts of (NdalphaRE1-alpha), 65.9-70.2 parts of (FebetaM1-beta) and 0.8-1.1 parts of B, wherein RE is optional one or more of La, Ce, Pr, Gd, Tb, Dy, Ho, Y and Sc, M is optional one or more of Co, Mo, V,Ti, Hf, Cu, Al, Nb, Zr and Ga, 50%</=alpha</=100%, and 90%</=beta</=100%. The permanent magnetic steel has the advantages that the permanent magnetic steel specially developed for the magnetic latching relay is free of power consumption in working state, small in size, lightweight, stable and reliable; the permanent magnetic steel is free of power consumption in the working state due to the factthat the permanent magnetic steel does not need to use coil energization to generate a magnetic field so as to keep a setting and resetting state. 本发明提供种用于磁保持继电器的永磁磁钢及其制备方法，其永磁磁钢合金组分是由29~33重量份（NdRE）、65.9~70.2重量份（FeM）和0.8~1.1重量
