METHOD OF MAKING MAGNETIC COMPONENT FOR DIRECT CURRENT APPARATUS ABSTRACT OF THE DISCLOSURE A method of making compact cores for use in direct current magnetic apparatus characterized by the steps of severing particles from thin, flat strips of ferrous alloys, said particles being substantially of elongated rectangular shape, annealing said laminations in decarburizing and deoxidizing atmosphere to improve the magnetic characteristics by reducing carbon to less than 0.01% and relieving stresses, compressing the par- ticles into a solidified configuration of the desired core component and annealing the core component at a temperature upwards of 2200°F in a non-oxidizing atmos- phere to improve the permeability and coercive force values.
