Description of Amorphous (water-atomised) Powder
Amorphous (water-atomised) powder possesses no crystalline structure unlike other magnetic materials. All atoms in an amorphous metal are arranged randomly. This results in a specific resistivity that is approximately threefold greater than that of its crystalline counterparts. Amorphous alloys are manufactured by cooling the melt at approximately 1 000 000 °C per second. This rapid cooling prevents the atoms from arranging themselves into a stable crystalline form. Consequently, a metastable amorphous structure is obtained.

Applications of Amorphous (water-atomised) Powder
Amorphous (water-atomised) powder is increasingly used in power supply and industrial transformers. It contributes to addressing problems related to global warming and energy conservation. Magnetic components based on amorphous metals are employed in power electronics, telecommunications devices, measuring instruments and electronic article surveillance systems. Some magnetic inductors are used in pulsed current devices, automotive ignition coils and electrical current conditioning systems. These applications are feasible because amorphous alloys permit faster flux reversal, lower magnetic losses and a more versatile adjustment of properties.
