Unveiling Everything You Need to Know About Nanocrystalline Core

2023-11-15

Nanocrystalline Cores are typically made from metallic-glass materials concentrated into well-defined, crystalline grains on the nanometer scale. Recently, they have been witnessed as an excellent alternative to nickel-iron because of their higher permeability, low power loss, and loads of other convincing features.

If you plan on crafting an equipment or invent a new technology or a product and are curious to know in depth about these cores, then you have landed at the right place! In this comprehensive article, we will delve into the key basics of Nanocrystalline Cores, their multiple types, and much more. So, without any further delay, let’s begin exploring!


A Glimpse into the Nanocrystalline Cores

Also known by the name metallic glass cores, Nanocrystalline Magnetic Cores have unique microstructure. When observed under high-power instruments, these cores seem to have nanocrystals, i.e., well-defined crystals per nanometer of the core material. These crystals are embedded in the amorphous or non-crystalline matrix, offering revolutionizing magnetic properties.

These cores are widely used to reduce energy loss and improve charging efficiency, shielding electromagnetic interference to mobile phones and wireless charging receiving terminals. You will find them in the car: wireless chargers, transformers, home appliances, and more.

How Nanocrystalline Cores Are Revolutionizing the Industry?

Nanocrystalline Cores are revolutionizing different industries, including electronics, magnetics, etc. Let's have a look at some of the tempting perks that you should consider when planning on getting cores for your industry.

 Minimized Core Loss – Hysteresis and eddy current losses are two of the most common losses observed during the working of typical cores. Owing to this, these cores have minimal power loss, reduced heat production, and increased overall system efficiency. Even at significantly high temperatures, losses are fairly reduced compared to other cores.

Increased Magnetic Induction – These cores come with increased magnetic induction that contributes to miniaturization, as small-sized cores would provide enough magnetic induction that a larger-sized core of other magnetic materials wouldn't.

Flexible Manufacturing – Their production is pretty flexible; you can customize them according to your desired impedance, frequency, and filtering characteristics. This property can prove extremely effective in electronics.

Higer Curie Temperature – Curie temperature refers to the temperature point when the magnetic materials lose their permanent magnetic properties and transform into induced magnets. Nanocrystalline Magnetic Cores have higher Curie temperatures, and the rate of change in the performance over temperature fluctuations is also linear.

Higher Frequency Properties – Moreover, they can operate on higher frequency, being a suitable component for emerging technologies, especially EV Charging. Owing to the higher saturation magnetic inductions, they can also manage higher current applications with strong interference.

In short, we have a plethora of reasons to back the revolutionization standards set by th Nanocrystalline Toroidal Cores. Let’s now have a look at the different types of these cores.  


The 8 Different Types of Nanocrystalline Cores

Nanocrystalline Cores can be divided into multiple types depending on your specific requirements and the applications you want to use these cores. Hop on to develop a better understanding of each type!

1. Nanocrystalline Toroidal Core

The very first type on our list is the Nanocrystalline Toroidal Core, which is more like woven doughnuts with a central hole. Its distinct shape allows for reduced magnetic interference and effective magnetic flux containment. Their common applications include high-frequency inductors and transformers with minimal core losses.

2. C-Core Nanocrystalline Cores

If you are into getting a Nanocrystalline Core with linearity in performance over different temperature ranges, ensuring precise current measurements, you must get C-core Nanocrystalline Cores. As the name suggests, these cores are normally C-shaped with applications in current sensing applications and Current Transformers (CTs).

3. U-Core Nanocrystalline Cores

These U-shaped Nanocrystalline Cores offer ease of connectivity when used in transformers and other devices, like inductors, etc. The best part? They have increased magnetic flux density.

4. E-Core Nanocrystalline Cores

These types boast shapes resembling the letter E and are utilized widely in power transformers, etc. Owing to the unique shape of the E-cross section, you can stay rest assured about the effective magnetic coupling and maximized flux that, in turn, contribute to the increased production of induced current.

5. ETD-Core Nanocrystalline Cores

Here comes another type with an ETD-shaped cross section used in converters and power supplies – everywhere you need compact, precise, and efficient magnetic components.

6. Multi-Aperture Nanocrystalline Cores

Apertures refer to holes, so these cores feature a plethora of holes on their body to ease the winding of the conductor around the core. You will find them commonly used in high-frequency conductors and common mode chokes where multiple windings are needed.

7. RM-Core Nanocrystalline Cores

Are you dealing with low-profile inductors and transformers? The RM-shaped cores will be your best bet. You can attain all the above-mentioned Nanocrystalline Core benefits from these; the major difference between the cores remains their shapes.

8. Custom Nanocrystalline Cores

Depending on the equipment you want to use, you can also customize these cores to your desired shape, size, and weight. Imagine you plan to invent advanced equipment, and none of the Nanocrystalline Core types seem to fit in. Just get in touch with premium manufacturers and get them customized per your requirements.

You can also ask them to set the specifications according to your demand, meaning the temperature tolerating capacity and more.

How to Choose Between the Different Nanocrystalline Cores?

Now you have all the details about the different types, you must wonder how to choose between them. Several factors account for these aspects, including permeability, capacity, etc. Let’s have a look at a few of these!

Operating Frequency and Core Shape Relation

The Nanocrystalline Core shape closely influences the operating frequency owing to the extent to which it minimizes the eddy current losses. So, depending on your required frequency, you can choose the most preferred shaped core.

Extent of Magnetic Permeability

Magnetic permeability, also known as magnetic capability, is indeed another important factor. The more the core is permeable, the more it allows the flow of magnetic lines of force through the material. Different types have distinct permeability; if lower, that type might have other notable advantages.  

Power Rating

Power rating refers to the power holding capacity. It also varies depending on the core type, with some cores being ideal for low-power applications while others being great for higher power levels.

Specific Application

Cores are widely used in transformers, inductors, and multiple other devices, with some requiring specific shape cores to ensure core loss constraints and ease of winding.

Environmental Considerations

Lastly, environmental considerations might require a core with specified environmental or thermal stability for effective working.

Budget Consideration

How much cost you are willing to spend is another important consideration. You will have to finalize between the different types, depending on which will prove more cost-effective and budget-friendly in the long run.

Size and Weight

Different types have their distinct size and weight specifications. For instance, a toroidal core ensures improved magnetic performance when being space-efficient. Sometimes, you may find multi-aperture cores more useful because of their ease of winding with their pre-built holes. This special winding style also reduces energy loss, so it's a worthy pick in most cases.
