PURPOSE:To produce a high permeability alloy improved in corrosion resistance and increased in workability by incorporating specific amounts of Ti, Ru, etc., into a 'Sendust(R)' type alloy containing specific percentages of Si and Al. CONSTITUTION:The high permeability alloy which has a composition consisting of, by weight, 6.0-12.0% Si, 4.0-8.0% Al, one or >=2 elements selected from Ti, V, Zr, Nb, Mo, Hf, Ta, and W in the amount of 0.01-5.0% in total in the case of >=2 elements, one or >=2 elements selected from Ru, Rh, Pd, Os, Ir, Pt, Au, and Ag in the amount of 0.005-5.0% in total in the case of >=2 elements, and the balance essentially Fe is prepared. Moreover, if necessary, 0.001-0.5%, by weight, C and 0.0005-0.1% N are incorporated, and further, 0.005-0.10% Mg is incorporated and also O content is controlled to <=0.001%. By this method, the corrosion resistance of the high permeability alloy as 'Sendust(R)' alloy can be improved and also workability can be increased. |
