Abstract: A bulk amorphous metal magnetic component has a plurality of layers of ferromagnetic amorphous metal strips laminated together to form a generally three-dimensional part having the shape of a polyhedron. The bulk amorphous metal magnetic component may include an arcuate surface, and preferably includes two arcuate surfaces that are disposed opposite each other. The magnetic component is operable at frequencies ranging from between approximately 50 Hz and 20,000 Hz. When the component is excited at an excitation frequency “f” to a peak induction level Bmax, it exhibits a core-loss less than “L” wherein L is given by the formula L=0.0074 f (Bmax)1.3+0.000282 f1.5(Bmax)2.4, said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively.

Abstract: A rapidly solidified amorphous metallic alloy is composed of iron, boron, silicon and carbon. The alloy exhibits in combination high saturation induction, high Curie temperature, high crystallization temperature, low core loss and low exciting power at line frequencies and is particularly suited for use in cores of transformers for an electrical power distribution network.
