Welcome to buyers to negotiate.

Types of wireless charging ferrite:
Ferrite: sintered by high-temperature ferrite sheet, has a high magnetic permeability, the material is hard and easy to crack, commonly used in the transmitter side of wireless charging. Depending on the type of ferrite, the magnetic permeability of the general ferrite is from a few hundred to a few thousand.
Wave-absorbing material: Alloy magnetic powder is added to plastic or rubber, and then processed and molded into a soft magnetic sheet. The soft magnetic sheet material is softer, the thickness is very thin, can be punched according to the shape and size of the spacer required by the wireless charging program, the customization system is higher, and commonly used in the wireless charging receiving end. The magnetic permeability of wave-absorbing materials generally ranges from tens to hundreds, basically not more than 300.
Alloys: alloys are seldom categorized into the magnetic separator inside, but I personally believe that the role of the magnetic separator is the same. Commonly used alloys include iron-silicon aluminum alloys and nickel-iron niobium alloys, with permeabilities generally greater than 8000.

wireless charging ferrite

Wireless charging ferrite is a material that uses Magnetic Resonance Coupling (MRCC) technology to enable wireless charging. This technology enables wireless charging by transferring energy from one electromagnetic field to another. Ferrite, a magnetic material with high permeability and low reluctance, is widely used in wireless charging devices.

In wireless charging devices, the ferrite material is usually used to make an electromagnetic resonance coupler, also known as a “resonator”. The resonator consists of two ferrite blocks, one of which is a transmitter that transmits electrical energy to the other block, the receiver. The receiver converts the energy to DC through a circuit that powers the wireless charging device.
Wireless charging ferrite technology has been used in several devices, such as cell phones and electric cars. This technology can provide convenient, safe, and efficient charging for people’s life.

Take wireless charging ferrite as an example, ferrite soft magnetic material plays a role in wireless charging in terms of magnetic conductivity and reduction of resistance, and magnetic shielding. The advantage of ferrite soft magnet is the cost, especially in the high-power transmitter selection, nanocrystalline soft magnet cost may be more than two times the ferrite soft magnet, then the cost performance advantage of ferrite soft magnet material is highlighted.

The advantages of wireless charging ferrite in wireless charging applications

1. Advantages of structure
Nanocrystalline magnetic sheet and ferrite magnetic sheet receiving ends are flat types, but to do shaped parts including watches, not a flat type structure, some magnetic sheet processing is impossible to process.

2. Mass production advantage
Ferrite is a traditional material, and the production capacity is very large, not in thousands of tons, but in tens of thousands of tons, and the annual shipment of ferrite is about 20,000 tons.

3. Reliability advantage
The specific temperature of wireless charging ferrite material is about two hundred degrees, but it is about one hundred degrees for receiving end material and has high acid and alkali resistance. Especially in the processing of nanocrystalline magnetic sheets, because of the introduction of some adhesive materials, if in the process of high-power like tens of watts, hundreds of watts, or several kilowatts of charging, its use of temperature is generally more than 120 degrees. The choice of rubber materials introduces a large number of costs. And, it may be 0.1 or a few layers of thickness may not reach the corresponding charging efficiency.

4. Cost advantage
Ferrite to do a large product advantage will be more obvious, the series of small power two products will be increasingly close, especially the cost of the receiving end. On the transmitter side, if you do some high-power, there may be three kilowatts or several kilowatts, if purely with a nano chip to do, it may not cost twice, and the small piece may be about twice.

Wireless charging ferrite products can be divided into receiver and transmitter, like the wifi function of a cell phone, the transmitter is similar to the wireless router; the wireless charging receiver is similar to the built-in wifi antenna of a cell phone; the technology of the receiver requires heat dissipation, thinness, high efficiency, mainly composed of the coil, magnetic material, chip, etc.;

Various magnetic isolators made of soft magnetic ferrite materials are used as the main components of wireless charging ferrite technology, which play the role of increasing the induction magnetic field and shielding the coil interference in wireless charging devices. Wireless chargers have higher requirements on soft magnetic ferrite material function and product size, reliability, etc., and higher requirements on the receiving end.

The primary magnetic materials used in wireless chargers are NdFeB permanent magnets, NiZn ferrite thin magnetic sheet, MnZn ferrite thin magnetic sheet, flexible ferrite magnetic sheet;


Wireless charging ferrite is a type of magnetic material used in wireless charging systems. This technology has been gaining popularity in recent years due to its convenience and ease of use. With wireless charging, users no longer need to plug in their devices to charge them, which can be especially useful for devices with limited port access or for those who frequently move around with their devices. Wireless charging ferrites are made from a variety of materials, including iron, nickel, and zinc, and are designed to enhance the efficiency of wireless charging systems.

One of the key benefits of using wireless charging ferrite is its ability to improve the charging efficiency of wireless charging systems. These ferrites are designed to reduce the amount of energy lost during the charging process, which can help to reduce the time required to charge a device. By minimizing energy loss, these ferrites help to optimize the transfer of energy from the charging pad to the device being charged, resulting in faster and more efficient charging.

Wireless charging ferrites are also known for their durability and long lifespan. These materials are designed to withstand the wear and tear of everyday use, making them ideal for use in a variety of electronic devices. They are also resistant to temperature fluctuations and electromagnetic interference, which can help to ensure that they continue to function properly even in challenging environments.

Another benefit of wireless charging ferrite is its versatility. These materials can be used in a wide range of applications, from smartphones and tablets to larger devices such as laptops and electric vehicles. They can also be customized to meet specific requirements, such as the size and shape of the charging pad or the amount of power required for charging.

In conclusion, wireless charging ferrite is an important component in modern wireless charging systems. Thanks to its ability to improve charging efficiency, durability, and versatility, this material has become increasingly popular among manufacturers of electronic devices. As technology continues to evolve, it is likely that we will see even more advanced wireless charging systems that rely on ferrite materials to deliver fast and efficient charging to a wide range of devices.

The Future of Wireless Charging Ferrite

As wireless charging technology continues to advance, it is likely that we will see more widespread adoption of wireless charging ferrite. Many electronic device manufacturers are already incorporating wireless charging into their products, and it is likely that this trend will continue.

In the future, we may see wireless charging pads integrated into furniture, such as tables and desks, making it even more convenient to charge our devices. It is also possible that we may see wireless charging pads integrated into public spaces, such as airports and coffee shops, allowing people to charge their devices on the go.
