Iron-based nanocrystalline ribbon

The iron-based nanocrystalline alloy is composed of iron, silicon, boron, niobium, copper and so on. When the iron-based amorphous alloy containing Cu and Nb is annealed above the crystallization temperature, a very fine grain structure will be formed, and the grain size is only 10-20 nanometers. This amorphous alloy is formed by special crystallization annealing The crystalline materials are called nanocrystalline alloys. Nanocrystalline materials have excellent characteristics such as high saturation magnetic induction, high magnetic permeability, low coercive force, low loss, good stability, high strength, toughness, wear resistance and corrosion resistance, etc., and have the best performance and price among metal soft magnetic materials. Compared with nanocrystalline alloy materials, it can replace silicon steel, permalloy and ferrite and become an ideal material for medium and high frequency transformers, transformers and inductance components.
