Current Status and Future Planning Prospect for Amorphous and Nanocrystalline Magnetic Cores

Amorphous and nanocrystalline materials are emerging metal soft magnetic materials, they have been widely used in fields such as aviation, aerospace, shipbuilding, as well as photovoltaics, wind power, and new energy vehicles. This article proposes the idea of establishing a standard system for amorphous and nanocrystalline magnetic cores by referring to soft magnetic ferrite cores and metal magnetic powder cores belonging to the same category of soft magnetic materials. The standard system for amorphous and nanocrystalline magnetic cores includes three parts: basic standards, product standards, analysis method standards and performance testing method standards. Basic standards include terminology and definitions, classification; The product standards include guidelines on dimension and the limits of surface irregularties for amorphous and nanocrystalline magnetic cores, as well as alloy standards. The analysis method standards include chemical analysis methods and physical analysis method standards; The standards for performance testing methods include electrical performance, power loss, and mechanical strength and so on.
