ABSTRACT:
Due to an Mo addition, to a known Co-Fe-Nb semi-hard magnetic material, the coercive force is enhanced without causing deterioration of the cold workability of the semi-hard magnetic material. In addition, the energy product, the residual flux density and the fullness factor are high according to the semi-hard magnetic material of the present invention. Such material is particularly suited for reed pieces of reed switches, which are mounted in a four wire crosspoint switch.
