This method for making a transformer core comprises the following steps: (a) providing amorphous metal strip material, (b) winding said strip material onto an arbor in superposed layers, thereby forming a multi-layered core form, (c) applying coats of powder to said strip material before the strip material is wound onto the arbor, thereby causing predetermined adjacent ones of said layers by to be separated small distances to reduce the space factor of the core form, and (d) annealing the core form while said powder coatings are present between adjacent layers, thus enabling the powder to lessen the tendency of adhesions to develop between adjacent layers of amorphous metal during annealing.
