Abstract
Provided is a magnetic core for transformers which is made at least in part of amorphous metal lamination layers. The lamination layers are coated on the edges with a low-stress, low-viscosity coating material which, when cured, becomes sufficiently rigid to support the lamination layers of amorphous material. The coating material can be applied to the entire edge surface of both sides of the core or only to select portions of the edges on either side. In either instance, the coating material is applied in a manner that allows built-in stresses to relax out before all the coating material is fully cured.
