Abstract
A method for making pressed magnetic components having a low core loss characterized by the steps of compacting a plurality of substantially rectangular particles of an oriented iron alloy having a silicon content of from about 2.5% to about 3.5% and a carbon content of up to 0.01% into a compact of predetermined configuration, and stress-relief annealing the compact in a non-oxidizing atmosphere so as to provide a magnetizable compact having low core loss.
