Introduction to Nanocrystalline

Nanocrystalline soft magnetic alloy is a kind of soft magnetic alloy with ultrafine grain size (~10nm) after proper crystallization annealing treatment of amorphous alloy. This new type of metal functional material has the following remarkable characteristics: short manufacturing process, one-step molding, energy saving; And by adjusting the composition of the alloy, the magnetostriction can be made close to zero, with more excellent soft magnetic characteristics. Its outstanding advantage is that it has both the high saturation magnetic induction intensity (BS) of the iron-based amorphous alloy and the high permeability and low loss of the cobalt-based amorphous alloy, which can well meet the performance requirements of high frequency and low loss, and the cost is low.
