SOFT MAGNETIC METAL POWDER, AND SOFT MAGNETIC METAL POWDER COMPACT CORE ARRANGED BY USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a soft magnetic metal powder compact core improved in core loss by use of soft magnetic metal powder improved in coercive force.SOLUTION: Soft magnetic metal powder comprises: B; and Fe and Ni as primary components. In the soft magnetic metal powder, the content of Ni is 30-80 mass%, and the total content of Fe and Ni is 90 mass% or more. The soft magnetic metal powder consists of metal particles 5 in which the content of B is 10-150 ppm; and each particle has, on its surface, a boron nitride coating 6.
