Detailed description of the invention
1. 1 kinds of magnetically soft alloys of embodiment and manufacture method thereof
In the alloy of the present embodiment, weight percent content is: Co49.0～51.0, V0.80～2.0, and impurity C is 0.004, P
Being 0.002, S is 0.004, and Cu is 0.04., Fe surplus；
Containing Nb in the alloy of the present embodiment, its weight percent content is 0.03-0.05；
In alloy, V content and coercitive relation are as shown in Figure 1: the content (%) of metal V is between 0.8-2, along with V content
Raising, coercivity becomes larger, and V content coercivity after 1.6 gradually tends towards stability.Thus, the content of V exceeds GB
(0.8-1.8) reaching 2.0, the coercivity of alloy is also quite stable, and therefore, the Ⅴ-permandur alloy of high vanadium also has brilliance
Magnetic property.
The processing technique of the present embodiment is:
