ABSTRACT:
Mono-directional magnetic anisotropy given to a Fe-Cr-Co straight tube by initial heat magnetization is converted into radial magnetic anisotropy by subsequent formation of one or more flange sections through plastic deformation which is perpetuated by final age-hardening in order to obtain an excellent configuration magnet well suited for electro-acoustic converters.
