Fe-Based Nanocrystalline Soft Magnetic Ribbon 1k107B

. What are Fe-based nanocrystalline ribbons?

Fe-based nanocrystalline ribbons are ultra-thin, soft magnetic alloy strips (typically composed of Fe-Si-B-Cu-Nb) produced via rapid solidification. Their microstructure consists of nanoscale crystalline grains (10-20nm) embedded in an amorphous matrix, offering exceptional magnetic properties such as high permeability, low core loss, and high saturation flux density.

2. What are the key advantages of nanocrystalline ribbons?

• High-frequency, low-loss performance: Superior to silicon steel in kHz-MHz applications.

• High permeability (μi): Up to 100,000+, outperforming ferrites.

• High saturation flux density (Bs): 1.2-1.4 T, ideal for high-power designs.

• Temperature stability: Operating range of -50°C to 150°C.

3. Typical applications of nanocrystalline ribbons?

• Power electronics: High-frequency transformers, inductors, common-mode chokes.

• Renewable energy: Solar inverters, EV charging stations.

• Consumer electronics: Wireless charging, UPS systems.

• Industrial: Switch-mode power supplies (SMPS), EMC filters.
