The atomic structure of an amorphous metal is different from that of normal metal.
Crystals form amidst the process of cooling heated metal. However, when heated metal is cooled quickly so as not to form crystals, it becomes amorphous and has a non-crystalline structure.
Amorphous metals, of which the main component is iron, have characteristics that are well suited for increasing the efficiency of motors. Compared to magnetic steel sheets which are conventionally used as the iron core of motors, amorphous metals experience one-tenth the core loss, and it is expected that they will contribute to energy conservation in electrical equipment.
