1. Preparation process: The preparation of nanocrystalline cores usually adopts special processes, such as rapid solidification, sol-gel, and heat treatment. The preparation process of traditional soft magnetic materials is relatively simple. The preparation process of nanocrystalline cores requires higher technical requirements and cost investment.

2. Magnetic permeability（ μ）： Nanocrystalline cores typically have higher magnetic permeability, which means they can more effectively conduct and concentrate magnetic fields. In contrast, traditional soft magnetic materials have lower magnetic permeability. High magnetic permeability enables nanocrystalline cores to provide better performance in applications such as sensors and inductors.

3. Magnetic saturation induction intensity (Bs): Nanocrystalline cores typically have higher magnetic saturation induction intensity, which means they can store more magnetic energy. In contrast, traditional soft magnetic materials have lower magnetic saturation induction intensity. This gives nanocrystalline cores advantages in efficient energy conversion and energy storage applications.

1. High saturation magnetic induction intensity: Nanocrystalline cores have a high saturation magnetic induction intensity, which means they can store more magnetic energy. This enables nanocrystalline cores to have higher efficiency and smaller volumes in energy storage and conversion applications.

2. Low hysteresis loss: Nanocrystalline cores have low hysteresis loss, which means that the energy loss generated during magnetic field changes is relatively small. This means that in high-frequency applications, nanocrystalline cores can reduce energy loss and heat generation, and improve system efficiency and stability.

3. High-temperature stability: Nanocrystalline cores have good high-temperature stability and can maintain their magnetic performance in high-temperature environments. This gives nanocrystalline cores advantages in high-temperature applications, such as high-temperature power electronic devices and automotive electrification.
