Iron-Based Nanocrystalline Ribbons market. Iron-based nanocrystalline alloys are amorphous materials formed by rapid solidification of alloys consisting mainly of iron elements and adding a small amount of Nb, Cu, Si and B elements. The amorphous materials can be obtained by heat treatment and dispersed on the amorphous matrix. They are called microcrystalline, nanocrystalline or nanocrystalline materials. The diameter of microcrystal is 10-20_suitable frequency range is 50 ... Read more
