Abstract
A magnetic alloy which contains not less than 0.03 weight percent but not more than 5.0 weight percent of P, not less than 0.01 weight percent but not more than 5.0 weight percent of at least one element of Ti, Nb, and Zr, not less than 2.5 weight percent but not more than 10 weight percent Si and the remaining part consisting mainly of Fe is disclosed. In the alloy, P is segregated on the grain boundaries thereof with a specified amount which results in a superior magnetic characteristics and workability represented by the fact that the alloy can be rolled.
Claims2
A magnetic alloy sheet containing not less than 0.03 weight percent but not more than 5.0 weight percent of P, not less than 0.01 weight percent but not more than 5.0 total weight percent of at least one element of Ti, Nb, and Zr, not less than 2.5 weight percent but not more than 10.0 weight percent of Si, and the remaining part consisting mainly of Fe, said alloy having been slow cooled after casting to cause P to be present on the grain boundaries thereof in an amount of more than 0.5 weight percent of the atoms which form said grain boundaries.
