Iron-based nanocrystalline common-mode filter inductor cores are core magnetic components specifically designed to address high-frequency electromagnetic interference (EMI) issues in modern electronic devices. Leveraging the unique microstructure and superior magnetic properties of iron-based nanocrystalline alloys, they play a crucial role in the field of electromagnetic compatibility (EMC).

Iron-based amorphous bulk alloys (also known as iron-based bulk metallic glasses) represent a significant product form of iron-based amorphous alloys. They refer to bulk amorphous alloy materials with centimeter-scale thicknesses, fabricated through specialized processes. Unlike traditional iron-based amorphous ribbons (which are only 20–80 μm thick), iron-based amorphous bulk alloys achieve a breakthrough from "micron-scale ribbons" to "centimeter-scale bulk materials" while maintaining their amorphous atomic structure, thereby opening up entirely new possibilities for the application of amorphous alloys.

Gapped cores refer to the intentional introduction of a non-magnetic space (i.e., an air gap) into the closed magnetic circuit of magnetic materials such as iron-based amorphous alloys or silicon steel sheets. Although the physical dimension of the air gap is typically extremely small (sometimes less than one millimeter), it significantly alters the flow of magnetic flux within the core, making it one of the most powerful yet subtle parameters in the design of magnetic devices. Cut cores represent a critical form in core manufacturing and processing. The core process involves using high-precision mechanical or laser cutting to machine continuous silicon steel strips or wound closed cores into specific shapes or dimensions.

Coated cores are industrial components in which the core parts of electromagnetic devices, such as motors and transformers (e.g., stators, rotors, or laminations), are covered with an insulating, anti-rust, or anti-corrosion protective film through a specialized coating process. Since these cores are typically fabricated from iron-based nanocrystalline, amorphous, or silicon steel sheets, robust interlaminar electrical insulation is essential to minimize eddy current losses. Consequently, surface coating serves as a critical manufacturing step to enhance core performance, durability, and product yield.

Square cores are a common cross-sectional shape for electromagnetic components such as transformers and reactors. They are manufactured by winding or stacking iron-based nanocrystalline, amorphous, or silicon steel sheets, followed by a shaping and setting process.
