A new type metal materials with special properties are not crystal structure which is different with the common alloy is often crystal structure which will arrange samples are regulated as atomic material remember them. Metallic glasses treasure special important is have very strong, rigid and flexible. Additionally also corrosion resistant as well as material. Metallic glasses important widely used in engineering, which is a magnetic soft valuable magnetic permeability higher. So this is easy to make a magnet. The breaking and magnetism. Loops hysteresis narrow and the loss of hysteresis energy less compared to the silicon steel.
