Advantages

1. High Saturation Magnetic Flux Density
   The saturation magnetic induction strength far exceeds that of ferrite soft magnetic materials. For example, iron powder cores can reach 1500 mT, iron-silicon-aluminum magnetic powder cores achieve 1050 mT, and high-flux magnetic powder cores reach 1300 mT. This characteristic prevents saturation in high-magnetic-field environments, making it suitable for high-power applications.

2. Excellent High-Frequency Performance
   Due to the insulation of metal powders by dielectric layers, eddy current losses are significantly reduced, making it suitable for medium-to-high-frequency ranges (1 kHz to MHz+). For instance, carbonyl iron powder cores perform exceptionally in high-frequency switching circuits and exhibit superior DC bias characteristics.

3. Low Loss and Frequency Stability
   Low loss and good frequency stability enable consistent performance across wide frequency ranges, particularly in dynamic scenarios like switching power supplies and inverters.

4. Stability Under AC/DC Superposition
   In applications with combined AC/DC fields (e.g., photovoltaic inverters, variable-frequency air conditioners), it effectively avoids permeability degradation, ensuring stable inductor performance.

5. Strong Magnetic Property Controllability
   By adjusting production processes (e.g., particle size, insulation layer thickness), cores with customized permeability and loss characteristics can be produced to meet diverse needs.

6. Temperature Stability and Reliability
   Performance remains nearly unchanged after aging treatment, and recycled cores can be refurbished, ensuring long-term magnetic stability.
