A method of controlling the eddy-current loss and increasing the permeability of sulfur-and-manganese-bearing, 2-81 Molybdenum Permalloy, pressed powder by maintaining the alloy at an elevated temperature in an air or other environment for a sufficient time to begin nucleation of a solid-solution precipitate which is evenly distributed within the grains of the alloy, but without permitting significant growth and combination of the precipitate into large particles or their migration to the grain boundaries, and annealing in a reducing atmosphere for a period of time sufficient to cause secondary recrystallization of the grains and dissolve the solid-solution precipitate.
