Iron-based nanocrystals are composed of iron, silicon, boron, niobium, and copper. 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 material is called nanocrystalline alloy. Nanocrystalline material has high saturation magnetic induction intensity, high magnetic permeability (low coercivity), low loss and good stability,
It has excellent properties such as high strength, toughness, wear resistance and corrosion resistance. As a nanocrystalline alloy material with the best price-performance ratio among metal soft magnetic materials, it can replace silicon steel, permalloy and ferrite as medium and high frequency transformers, transformers, transformers, etc. Ideal material for inductive components.
