Nanocrystalline Soft Magnetic Core - High Permeability - Low Loss - Ntermediate frequency transformer - Power transformer

Nanocrystalline soft magnetic core is fabricated from an iron - based alloy with nanoscale crystalline structures, achieved through rapid solidification and precise heat treatment. This unique microstructure endows it with superior magnetic properties that bridge the gap between amorphous and conventional crystalline materials. As a key component in modern electronics, it is widely adopted in high - frequency power conversion, signal processing, and energy storage systems, enabling smaller, more efficient device designs.Nanocrystalline Soft Magnetic Core - Advanced Magnetic Component for High - Frequency Applications

Ultra - High Magnetic Permeability

The nanocrystalline structure provides extremely high initial permeability (up to 100,000), allowing efficient magnetic flux induction with minimal excitation current. This feature is critical for reducing core size in inductors and transformers while maintaining high energy transfer efficiency.

Low Core Loss at High Frequencies

Compared to traditional silicon steel or ferrite cores, nanocrystalline cores exhibit significantly lower hysteresis and eddy - current losses even at frequencies up to 100kHz. This makes them ideal for high - speed switching power supplies and renewable energy inverters, where minimizing heat generation is essential for system reliability.

Excellent Temperature Stability

With a Curie temperature above 500°C, these cores retain stable magnetic performance across a wide temperature range (-40°C to 130°C). This stability ensures consistent operation in harsh industrial environments and automotive applications.

High Saturation Flux Density

Featuring a saturation flux density of 1.2 - 1.8T, nanocrystalline cores can handle high magnetic fields without distortion, making them suitable for high - power energy storage devices and inductive components in electric vehicles.
