Amorphous alloys are metals and alloys that have no long-range order in their atomic arrangements. The traditional metal or alloy has regular crystal structure, while the amorphous alloy breaks the original regular crystal structure and presents a long-term disordered structure in the rapid cooling state, which is very similar to the common liquid in structure.

Iron based amorphous alloy is a kind of amorphous alloy widely used in transformer.Its iron loss rate is one fifth of the traditional silicon steel material. It can replace the traditional silicon steel to do distribution transformer can save energy of 60-70%, is worthy of energy-saving material. 

The amorphous alloy not only has a lower loss rate than the traditional silicon steel, but also has a much shorter preparation process than the silicon steel, which greatly reduces the cost of preparation.
