Title:
HIGH PERMEABILITY MAGNETIC ALLOY
Document Type and Number:
Japanese Patent JP2001192784
Kind Code:
A
Abstract:
To provide an alloy having stably high permeability in an Fe-Ni alloy having an Ni content of 30 to 44 mass %.
This alloy has a composition containing, by mass, 30 to 44% Ni, ≤1.0% Si, ≤1.0% Mn, and the balance Fe with inevitable impurity elements, and by controlling the crystal orientation properties, the value of P in the {200} plane is regulated to 3.0 or less. Preferably, 0.0020 to 0.030% O is incorporated into the above chemical components. It is found that, in the case the P value in the {200} plane exceeds 3, the maximum permeability is made low.
