Nanocrystalline Cores / Nanocrystalline Material
Nanocrystalline material is characterized by features such as high magnetic saturation, high magnetic permeability, low coercivity, low losses (excellent efficiency due to low AC losses), high temperature stability over a wide temperature range, high wear resistance, and corrosion resistance, offering the best price-performance ratio among metallic soft magnetic materials. The Fe-based nanocrystalline strip alloy consists of iron, silicon, barium, niobium, and copper. The nanocrystalline Allox material can replace silicon steel, permalloy, and ferrite and is the ideal material for medium- and high-frequency transformers, power transformers, and other inductors.
Applications:
- EMC common-mode and differential-mode filter chokes
- Cores for switching power supply transformers and control transformers
- CT/VT cores with varying accuracy
