Liquid amorphous metal alloy is manufactured into shaped laminations ready for assembly in an inductive component in one process. The rotating chill surface to which the melt is delivered has high thermal conductivity metal in a pattern corresponding to the shaped lamination and is surrounded by thermally insulating material. Melt coming in contact with the high thermal conductivity metal becomes amorphous and that contacting the thermally insulating areas cools more slowly and becomes crystalline. The brittle crystalline scrap is broken away from the strip of laminations and is collected and recycled to the melt.

A method of fabricating geometrically shaped laminations of amorphous metal alloy for inductive components comprising the steps of delivering a stream of liquid alloy melt against a relatively rapidly moving chill surface having high thermal conductivity material in a pattern corresponding to the shaped lamination being processed which is at least partially surrounded by low thermal conductivity material, quenching the alloy melt at different cooling rates to continuously form a ribbon of solidified metal which separates from the chill surface and is composed of ductile amorphous metal in the shaped lamination pattern and brittle crystalline metal in other areas, and removing the crystalline metal areas of the ribbon to leave only a strip of amorphous metal laminations.
