Noncrystalline electromagnetic alloys are a new material with excellent properties.On the basis of practices,the paper introduces compositions and preparation methods of cobalt based,iron nickle based,iron based noncrystalline electromagnetic alloys bands,and the preparation method and the heat treatment technologies of the noncrystalline core.Through application contrast experiments of power transformers and pulse transformers made of developed noncrystalline core and those made of the core of traditional magnetic materials,we have proved that noncrystalline electromagnetic alloys own the properties of high saturation intensity of magnetization,low magnetic loss,high magnetoconductivity as well as wide frequency range.
