What is Nanocrystalline Core?

Nanocrystalline core refers to the soft magnetic material that possesses numerous crystalline grains of dimensions that fall within the nanometer scale. Such cores are made up of amorphous alloy ribbons through a process referred to as annealing. The process makes use of various strategies like high-speed solidification, rapid cooling, and thermal management as a way of achieving the specific nanocrystalline metallic structure that is required.

Due to the increased interest in high-frequency applications, nanocrystalline cores are being sought after for their many advantages. In this article, we will be taking a detailed look at the advantages that come along with using nanocrystalline cores in high-frequency applications.

Advantages of Nanocrystalline Core for High-Frequency Applications

1. Low Core Losses

Core loss is the cause of energy dissipation consumed by a magnetic core when subjected to an alternating magnetic field. Nanocrystalline cores are known to have exceptionally low core losses compared to other conventional magnetic cores. This low core loss feature makes nanocrystalline cores the most suitable for high-frequency applications. With their high permeability, low losses, and low coercivity, nanocrystalline cores can operate at high efficiency without the worry of power loss.

2. High Permeability

Permeability is the degree to which a core can easily conduct magnetic flux within its structure. In most high-frequency applications, high permeability is essential to ensure maximum magnetic field strength within the core. Nanocrystalline cores possess high permeability, which helps transfer a considerable amount of energy through the core. The high permeability feature of nanocrystalline cores makes them ideal for high-frequency transformers and inductors.

3. Excellent Temperature Stability

Temperature stability is a critical factor in the determination of the effectiveness, reliability and overall performance of magnetic cores in high-frequency applications. The unique feature of nanocrystalline cores is their ability to remain extremely stable, even under severe temperature conditions. Unlike ferrite cores that exhibit unstable permeability at high temperatures, nanocrystalline cores can retain their properties in a wide range of temperatures, thus rendering them suitable for several high-frequency applications.

4. High Saturation Flux Density

Saturation flux density is the maximum amount of magnetic flux a core can contain. Nanocrystalline cores possess high saturation flux density, which makes continuous use at high induction levels possible without exhibiting a significant rise in core losses. Additionally, the low coercivity of nanocrystalline cores makes it an ideal candidate for high-frequency applications like power electronics.

5. Wide Application Range

Nanocrystalline cores are versatile and can ideally suit numerous high-frequency applications. The ideal high-frequency applications that mandate the use of nanocrystalline cores include power electronics, power restoration, inductive components, current transformers, magnetic sensors and high-frequency transformers. Due to their range of advantages, nanocrystalline cores are suitable for narrowband and broadband applications, making them a cost-effective solution.


In summary, the unique features of nanocrystalline cores make them the best choice for use in high-frequency devices like inductive components, magnetic sensors, current transformers, high-frequency transformers and many other high-frequency applications. The advantages of low core losses, high permeability, wide application range, excellent temperature stability, and high saturation flux density, make nanocrystalline cores a worthy investment that pays off with unparalleled performance and reliability.
