The invention relates to a component of rare earth permanent magnet material, and the atomic percents of the material are Re(x)Fe(100x-z-a-b-c)B(z)Nb(a)Al(b)M(c), wherein x=12-16, z=5.5-6.5, a=0.05-1, b=0-0.8, and c=0-3. Re stands for rare earth elements, which comprises one or more of Nd, Pr, Gd, Ho, Dy and Tb. By adding Nb, Hcj can be improved, the rectangle degree of J-H demagnetization curve can be improved, and the temperature stability of the product can also be improved; and by adding Nb, the amount of Dy and Tb in heavy rare earth can be reduced, and the cost of the material can also be reduced. |
