Abstract
Official abstract text for this publication.
A soft magnetic metal powder includes a plurality of soft magnetic metal particles composed of an Fe—Co based alloy. The Fe—Co based alloy includes 0.50 mass % or more and 8.00 mass % or less of Co and a remaining part composed of Fe and an inevitable impurity. A soft magnetic metal powder includes a plurality of soft magnetic metal particles composed of an Fe—Co based alloy. The Fe—Co based alloy includes 0.50 mass % or more and 8.00 mass % or less of Co, 0.01 mass % or more and 8.00 mass % or less of Si, and a remaining part composed of Fe and an inevitable impurity. The present invention can provide a soft magnetic metal powder or so having a favorable corrosion resistance.
