The world of transformers and inductors has changed greatly over the years with the introduction of newer materials. Two such materials are amorphous cores and
nanocrystalline cores, but what is their difference? In this blog post, we will explore the differences between amorphous cores and nanocrystalline cores and how they鈥檙e different in terms of structure, performance, price, and more. We will also discuss why you may want to choose one core material over another for your particular application. Read on to learn more about these two types of transformer cores and how you can best utilize them!
What is an
amorphous core?
Amorphous cores are made up of randomly arranged atoms, without any kind of long-range order. This makes them difficult to study using traditional methods like X-ray diffraction. Nanocrystalline cores, on the other hand, have a more well-defined structure, with crystals that are just a few nanometers in size.
What is a nanocrystalline core?
A nanocrystalline core is a type of magnetic core made from nanocrystalline materials. These cores are composed of very small crystals, typically measuring just a few nanometers in diameter. This makes them much smaller than the grains found in traditional amorphous cores.
One of the benefits of using nanocrystalline cores is that they can be made with a much higher iron content than amorphous cores. This allows for increased magnetic flux density and improved power density. Nanocrystalline cores also have lower hysteresis losses, making them more efficient than amorphous cores.
The difference between amorphous cores and nanocrystalline cores
Amorphous cores are made of non-crystalline material, while nanocrystalline cores are made of very small crystals. The main difference between the two is that amorphous cores have a lower magnetic saturation and a higher coercivity than nanocrystalline cores. Nanocrystalline cores also have a higher Curie temperature than amorphous cores.
Which type of core is best for which application?
Amorphous cores are best for high-frequency applications because they have low hysteresis and eddy current losses. Nanocrystalline cores are best for power applications because they have high saturation flux density and low coercivity.
Conclusion
In conclusion, amorphous cores and nanocrystalline cores are similar in many aspects but have their own unique advantages. Amorphous cores are mainly used for low power applications due to their excellent magnetic properties and high efficiency, while nanocrystalline cores offer higher saturation flux densities which makes them ideal for use in higher power applications. Depending on the application, either type of core can be a viable option.
