Iron-silicon alloy powder magnetic cores and method of manufacturing the same

摘要

An Fe-Si alloy powder magnetic core comprises an alloy powder of an average particle diameter of 10-100 mu m, produced by water atomization, in which the composition by weight of the alloy powder is 2-12% silicon and 0.05-0.95% oxygen with the balance being essentially iron. The process of manufacturing the powder magnetic core is also disclosed.
