摘要： A process for manufacturing a reclaimed alloy material includes the steps of crushing a magnetic core including an amorphous alloy ribbon; putting a prepared organic solvent and crushed pieces obtained in the step of crushing into a container and putting the crushed pieces into contact with the organic solvent in the container; selectively discharging the organic solvent from the container after putting the crushed pieces into contact with the organic solvent; and evaporating, after discharging the organic solvent, the organic solvent remaining in the container. The crushed pieces, removed from the container after the organic solvent is evaporated, is reused as a reclaimed alloy material.
