Influence of the silicon content on the AC magnetic property was studied on the sintered 18Cr-2Mo-Fe magnetic alloy. The highest DC and AC magnetic properties were attained at the content of two-percent silicon. The lowering of the properties was observed at the three-percent silicon or above. The density and the DC magnetic property of sintered alloy was improved with the rise of sintering temperature, but the AC magnetic property indicated a decrease after an increase. This may be attributed to the change of the electrical resistivity originated in the porosity. The highest DC magnetic property and the increase of electrical resistivity are believed to be caused by the improvement of AC magnetic property at the content of two-percent silicon. The lowering of AC magnetic property above three-percent silicon may be due to the decrease of density resulted from the decrease of the press-compatibility.
