PURPOSE:To improve the corrosion resistance of an Fe-Al-Si alloy without deteriorating the superior magnetic characteristics by combinedly adding a Pt group element and Sn to the Fe-Al-Si alloy. CONSTITUTION:This alloy consists of, by weight, 3-16% Si, 2.5-17% Al, 0.001- 4.0% of >=1 kind of Pt group element, 0.01-3.0% Sn and the balance chiefly Fe. Less than the lower limits of the Pt group element and Sn do not distinctly produce the effect, and more than the upper limits of them deteriorate remarkably the magnetic characteristics and make the alloy impractical. By this method the wear resistance and machinability can be also improved. By further adding an adequate amount of an element such as Ti or V as a secondary component, the corrosion resistance can be improved furthermore by the synergistic effect. |
