  • METAL POWDER, GREEN COMPACT THEREOF, AND METHOD FOR PRODUCING THEM
    Publication number: 20230191481
    Abstract: A metal powder capable of producing a dust core having a high saturation magnetic flux density, excellent rust resistance, and a low iron loss. The metal powder includes from 1.0% to 15.0% of Si, from 1.0% to 13.0% of Cr, from 10 ppm to 10000 ppm of Cl, from 100 ppm to 10000 ppm of S (sulfur), and from 0.2% to 7.0% of O (oxygen) by mass concentration, the remainder including Fe and unavoidable impurities, in which the average particle diameter of the metal powder is from 0.1 ?m to 2.0 ?m. This facilitates the production of a dust core having a high magnetic flux density, excellent rust resistance, and a low iron loss.
