Product Description

1. Definition and Composition

Amorphous cores are a type of magnetic core made from amorphous alloys, also known as metallic glasses. These alloys are formed by rapidly cooling molten metal, which prevents the atoms from arranging themselves into a regular crystalline structure. Instead, the atoms in amorphous cores have a disordered, non - crystalline arrangement.

Typically, amorphous core materials are composed of a combination of transition metals such as iron (Fe), nickel (Ni), and cobalt (Co), along with elements like boron (B), silicon (Si), and phosphorus (P). For example, iron - based amorphous alloys, which are widely used in power - related applications, mainly consist of iron as the base metal, with silicon and boron added to enhance their magnetic and other properties.

Shaping:

 First, the specific alloy composition is melted at extremely high temperatures. The melting process requires careful control of temperature and the proportion of each element in the alloy to ensure the desired properties of the final product.

 The molten metal is then rapidly cooled in a process called quenching. This rapid cooling rate, which can be as high as millions of degrees Celsius per second, is crucial in preventing the formation of a crystalline structure. As a result, an amorphous material is obtained.

 After quenching, the amorphous alloy is usually formed into thin ribbons. These ribbons can be further processed into different core shapes, such as toroidal (ring - shaped), cut cores, or other custom - designed shapes according to specific application requirements. For example, toroidal amorphous cores are popular in applications where high magnetic efficiency and low electromagnetic interference are required.

Advantages

Low Core Losses: Amorphous cores exhibit remarkably lower core losses. The non - crystalline structure reduces both hysteresis losses (due to the more efficient magnetization and demagnetization process) and eddy - current losses (as the disordered atomic arrangement restricts the flow of eddy currents). In power transformers, using amorphous cores can reduce no - load losses by up to 70% - 80% compared to traditional silicon - steel cores. This leads to significant energy savings, especially in applications where the transformer operates continuously.
High Magnetic Permeability: They have high magnetic permeability, which means they can efficiently conduct magnetic flux. This property is essential for applications that require high - performance magnetic components. For instance, in inductors and transformers, high magnetic permeability allows for better energy transfer and higher power density, enabling the design of smaller and more efficient electrical devices.
Good Thermal Stability: Amorphous cores possess excellent thermal stability. They can maintain their magnetic properties over a wide temperature range. Even in high - temperature environments, the reduced core losses also contribute to lower heat generation, ensuring the stable operation of electrical equipment. This makes them suitable for applications in power electronics, automotive electronics, and industrial settings where temperature variations are common.
High Saturation Magnetization: Amorphous cores often have relatively high saturation magnetization values. This characteristic allows them to handle higher magnetic fields before reaching saturation, which is beneficial for applications that need to process large amounts of magnetic energy, such as in some high - power transformers and magnetic amplifiers.

Applications

Power Transformers:

Inductors and Chokes: Amorphous cores are commonly used in inductors and chokes, which are important components in power supplies and many electronic circuits. The low losses and high magnetic permeability of amorphous cores enable inductors to store and release energy more efficiently, ensuring stable current output in power supplies and filtering out unwanted electrical noise in electronic devices.


 

 In the power grid, amorphous - core power transformers are increasingly being used for energy distribution and transmission. Their low - loss characteristics help improve the overall efficiency of the power grid, reducing energy waste during the transformation and distribution of electricity. This is particularly important for large - scale power systems, as the cumulative energy savings from using amorphous - core transformers can be substantial.

Magnetic Amplifiers: 

Electric Vehicles:

They are employed in magnetic amplifiers, which are used in electronic control systems. The high saturation levels and low losses of amorphous cores allow for precise and reliable amplification of weak magnetic signals, making them ideal for applications such as in some industrial control systems and certain types of sensor signal processing.
High - Frequency Devices: Amorphous cores are well - suited for high - frequency applications, such as in high - frequency transformers, converters, and inverters. Their ability to maintain low core losses and high magnetic performance at high frequencies makes them an excellent choice for modern high - speed communication equipment, switching power supplies, and other devices that operate in the high - frequency range.

 In the field of electric vehicles (EVs), amorphous cores are used in power electronics systems. They contribute to the overall efficiency and performance of EV charging stations and motor drives. For example, in the motor drives of EVs, amorphous - core inductors can help improve the efficiency of the motor control system, leading to longer driving ranges and better performance of the electric vehicle.
