The writers carried out a series of experiments on the effect of Si on the magnetic properites with four varieties of typical precipitation magnetic alloys, namely, Fe-Ni-Al alloy, Fe-Ni-Al-Co-Cu alloy, anisotropic Fe-Ni-Al-Co-Cu, and Fe-Ni-Al-Co-Cu-Ti alloys. From this experiments,the following results were obtained. Generally,the coercive force decreases as the Si content increases for each magnetic alloys.The residual induction increases as the Si content increases for the magnet alloys of non-magnetic field treatment. In the case of anisotropic Fe-Ni-Al-Co-Cu and Fe-Ni-Al-Co-Cu-Ti alloys,residual induction increases as the Si content increases up to about 1%, but decreases remarkably when it rises beyond 1%.And then the desirable Si content for each type of magnet alloys was decided.
