Abstract

PURPOSE: To produce a case material which is superior in magnetic characteristic and wear resistance, by sintering after compacting the material powder, which are so mixed that the permalloy composition is obtained, and by rolling and working the obtained sintered material.
CONSTITUTION: Material powders are so mixed and prepare that the object ermalloy composition can be obtained. That is, mixture powders of Fe powder and Ni powder or Fe-Ni alloy powder is used as the material powders for base components, and another powder including components for modification are added as required. The powders are mixed sufficiently and are charged in, for example, a rubber vessel and are subjected to compact by hydrostatic pressure compression and so on. Next, the obtained green compact is sintered at a high temperature in vacuum, the reducing gas atmosphere, or the inert gas atmosphere. Next, the sintered material is rolled and is worked into a thin plate, for example, about 0.4mm thick. This thin plate is the main case material for magnetic head.
