Nanocrystalline coresWith the continuous development and development of emerging application markets such as 5G, new energy vehicles, photovoltaic energy storage, and smart cities, the requirements for power devices are also sharply deepening. The frequently rejected power devices make device companies sigh. Compared with traditional magnetic powder cores, amorphous and nanocrystalline magnetic powder cores have excellent comprehensive performance, which enriches the choice of power device materials.
It is understood that the atomic structure of amorphous alloys has the characteristics of short-range order, long-range disorder, no crystal grains in the organization, and the existence of grain boundaries. Excellent magnetic properties, excellent mechanical properties, super corrosion resistance. Compared with the hardness of traditional alloys before and after annealing, the former has the advantages of high strength and superplasticity. Nanocrystalline has many advantages such as ultra-low core loss, excellent DC bias characteristics, excellent frequency characteristics, good temperature stability, and high cost performance.
