Núcleo magnético nanocristalino has high Bs, high effective permeability, high DC bias stability, high temperature stability, wide frequency adaptability, low power consumption, low-cost new soft magnetic material, applied to high power, high frequency, Miniaturized, high conversion rate switching power supply transformers and chokes.
Nowadays, solar energy industry inverters, hydropower, air power, and electric energy conversion and charging for hybrid vehicles have a great market space and future, because the performance of nanocrystalline magnetic cores has extremely high controllability.
The nanocrystalline magnetic core undergoes surface insulation treatment, and is uniformly mixed with the bonding agent, then pressed into shape and annealed. There are basically three ways to obtain nanocrystalline powder: amorphous strips are crushed after annealing and crystallization, mechanical alloying, and molten alloy atomization. At present, mechanical alloying is still in the laboratory research stage, and the amorphous strip crystallization method is produced in small batches by a few companies in China, but the market cannot be expanded due to cost reasons. Compared with other methods, the molten alloy atomization method has high efficiency and low cost. Its disadvantage is that the powder produced has low amorphous content and high loss.
