difference between neodymium magnet and ferrite magnet

2020-09-23



As a magnetic material often used in the industrial field, magnets are developing rapidly in the magnet market. Many magnet buyers may have a certain understanding of magnet materials such as neodymium iron boron strong magnets, permanent magnets, etc. What are the attributes of ferrite magnets? What are the differences between NdFeB strong magnets and ferrite magnets? Zhongke magnet manufacturing company compares the difference between them for everyone.


Introduction to ferrite magnet: It is a permanent magnet mainly made of sro or Fe2O3.

What is the difference between ferrite magnet and neodymium magnet:


Ferrite magnet is a kind of metal oxide with magnetism. The magnetic properties of ferrite have changed to a higher magnetic permeability at high frequency. The magnetic force is usually 800-1000 Gauss. It is often used in sound boxes, speakers and other equipment.

Neodymium magnets are cost-effective and have good mechanical properties. In the state of bare magnets, the magnetic force can reach about 3500 Gauss. Neodymium magnet belongs to the third generation of rare earth permanent magnet materials with small size, light weight and magnetism strong characteristics.




Compare ferrite magnet and neodymium in performance and cost aspects:

1. Ferrite magnet is inexpensive, it has high temperature resistance, such magnet is not easy to oxidize, and it has poor magnetic force. NdFeB magnet has a higher price, lower temperature resistance, easy oxidation, but with strong magnetism.

2. Ferrite magnet is large in size, troublesome in transportation, and slow in product shipment. Neodymium magnet is small in size, convenient to transport, and fast in shipping.

3. NdFeB magnet is mainly used in printing and packaging, electronics, electrical appliances, mining equipment and other fields. Ferrite magnet is mainly used in large machinery.

The advantages of neodymium iron boron magnets are high cost performance and good mechanical properties; the shortcomings are that the Curie temperature point is low, the temperature characteristics are poor, and it is easy to pulverize and corrode. It must be achieved by adjusting its chemical composition and adopting surface treatment methods. Improvements can meet the requirements of practical applications. NdFeB magnet belongs to the third generation of rare earth permanent magnet materials. It has the characteristics of small size, light weight and strong magnetism. It is currently the magnet with the best performance-to-price ratio and is known as the magnet king in the field of magnetism. The advantages of high energy density make NdFeB permanent magnet materials widely used in modern industry and electronic technology. In the state of bare magnetism, the magnetic force can reach about 3500 Gauss.

Nowadays, the application of powerful neodymium iron boron magnets is very extensive, and it is still the dominant magnet in the magnet market. It is currently the magnet with the best performance-to-price ratio and is known as the magnet king in the field of magnetism.


Ferrite magnet is a metal oxide with ferromagnetism. In terms of electrical properties, the resistivity of ferrite is much greater than that of metal and alloy magnetic materials, and it also has higher dielectric properties. The magnetic properties of ferrite also show high permeability at high frequencies. Therefore, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current. It is a non-metallic magnetic material and is a composite oxide (or ferrite) of ferric oxide and one or more other metal oxides. The magnetic force is usually 800-1000 Gauss, which is often used in sound boxes, speakers and other equipment.

In summary, the difference between ferrite magnet and ndfeb magnet could be concluded as the followings:

1.Different materials, this is the essential difference

2. The second is the difference between the coercive force, remanence and magnetic energy product parameters between the highest grades. Ferrites are relatively weak. ...)

3. The last is temperature resistance: ferrite products: below 80-300 degrees NdFeB high temperature can reach about 80-200 degrees, the current highest is 220-250.
