The application of amorphous cores and nanocrystalline cores has seen significant growth in the fields of wireless charging and electric vehicles, mainly due to their excellent magnetic properties and high-frequency characteristics. In the wireless charging sector, amorphous cores and nanocrystalline cores are gradually replacing traditional ferrite materials as the next generation of magnetic isolation materials, thanks to their high permeability, low losses, and high saturation magnetic induction strength. Nanocrystalline materials, with even superior performance, are increasingly taking the place of ferrites as the new generation of magnetic materials for wireless charging. According to QYResearch, the global market size for nanocrystalline soft magnetic alloys grew from $165 million in 2015 to $242 million in 2019, with a compound annual growth rate of 10.08%. In the field of electric vehicles, amorphous and nanocrystalline alloys are widely used as ideal soft magnetic materials in the motors and electrical systems of electric cars. Energy-efficient motors made from amorphous materials are particularly suitable for electric vehicles, while high-frequency filtering inductors made from ultrathin nanocrystalline strips can significantly optimize vehicle performance and efficiency. For example, the application of amorphous alloys in the boost converters of hybrid vehicles meets the demands for high current and compact design, featuring high saturation flux density, low iron losses, and excellent frequency characteristics. Additionally, with the rapid development of the electric vehicle industry, the construction of supporting charging facilities is progressing simultaneously, raising the technical and reliability requirements for magnetic components. Overall, amorphous cores and nanocrystalline cores, with their outstanding magnetic properties and high-frequency characteristics, have found extensive applications in wireless charging and electric vehicles. As technology advances and market demand grows, their application prospects will become even broader.
