Ferrite magnet ferrite magnetic steel

Ferrite magnet: Ferrite magnet has strong anti-demagnetization performance. Ferrite magnets are hard and brittle, requiring special machining process. Because the opposite magnet is oriented in the manufacturing direction, it needs to be magnetized in the selected direction, while the same magnet can be magnetized in any direction because it has no orientation, although a slightly stronger magnetic induction will be found on the side of the pressure surface that is usually the small. Due to its low cost, ferrite magnetic steel is often used in the field of electroacoustic equipment, such as speakers, headphones, etc.
●The shape of ferrite magnet is the same as that of NdFeB magnet, which can be customized according to customer needs. It can also be divided into square, ring, tile, circular cylinder, including special-shaped magnets. Essentially, the difference between ferrite magnet and NdFeB magnet is that its performance is weaker than that of NdFeB magnet, but its cost is lower and more affordable, and its performance price ratio is higher. Ferrite magnet can be divided into ferrite magnetic steel and ferrite magnetic tile according to its use. The magnetic tile has better air tightness and higher efficiency. The difference between the tile and the straight plate is that the tile can improve the efficiency of the motor at high speed. Because the magnetizing surface of the straight plate magnetic steel is always straight, it cannot achieve the efficiency of the magnetic shoe under the condition of ensuring the air gap is unchanged. The electric vehicle motors all use silicon steel stator. The higher the working frequency, the greater the iron loss, and the magnetic shoe can solve this problem. At the same speed, the working frequency of the silicon steel sheet will also be reduced, and the iron loss will be relatively reduced, The other differences are negligible. Usually, high-power motors choose more magnetic pads.

What is Ferrite magnet ferrite magnetic steel

Ferrite magnet or ferrite magnetic steel is a type of permanent magnet made from a composite of iron oxide (Fe2O3) and either strontium carbonate (SrCO3) or barium carbonate (BaCO3). These magnets are also known as ceramic magnets due to their brittle and ceramic-like texture.
Ferrite magnets are widely used type of permanent magnet due to their low cost, high magnetic field strength, and good resistance to corrosion and demagnetization. They are often used in applications such as electric motors, speakers, and refrigerator magnets. However, they are not as strong as other types of permanent magnets, such as neodymium magnets or samarium cobalt magnets.

Advantages of Ferrite magnet ferrite magnetic steel

Ferrite magnets, or ferrite magnetic steel, have several advantages over other types of permanent magnets:
1. Low Cost: Ferrite magnets are economical type of permanent magnet available on the market. They are made from relatively inexpensive raw materials, making them an affordable option for many applications.
2. High Coercivity: Ferrite magnets have high coercivity, which means that they can maintain their magnetic properties even in the presence of external magnetic fields. This property makes them ideal for use in applications where the magnet is subjected to high magnetic fields.
3. Corrosion Resistance: Ferrite magnets have excellent corrosion resistance, which makes them ideal for use in harsh environments. They are also resistant to demagnetization, which means that they can maintain their magnetic properties even after being exposed to high temperatures or strong magnetic fields.
4. Good Stability: Ferrite magnets have a stable magnetic performance over a wide range of temperatures. They can operate at high temperatures without losing their magnetic properties, which makes them ideal for use in applications that require high-temperature stability.
5. Easy to Manufacture: Ferrite magnets are easy to manufacture and can be produced in large quantities at a relatively low cost. They can be manufactured in various shapes and sizes, making them suitable for a wide range of applications.
Overall, the advantages of ferrite magnets make them a popular choice for many applications, including electric motors, speakers, magnetic separators, and refrigerator magnets.
