Difference between high-performance permanent ferrite magnet and neodymium iron boron magnet
Feb 01, 2019

There is a big difference between high-performance permanent ferrite magnets and neodymium-iron-boron magnets. High-performance permanent magnet ferrite magnets are ferromagnetic metal oxides. In terms of electromagnetic steel manufacturer characteristics, ferrite has a much higher electrical resistivity than metal and alloy magnetic materials, and has a higher dielectric function.

 

The magnetic function of high-performance permanent magnet ferrite magnets also exhibits high magnetic permeability at high frequencies. Therefore, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak electricity. A non-metallic magnetic material is a composite oxide (or orthoferrate) of ferric oxide and one or more other metal oxides. The magnetic force is generally 800-1000 Gauss, which is often used in speakers, speakers and other instruments.

 

NdFeB magnets also have outstanding mechanical properties, but they have low temperature points, poor temperature characteristics, and are easy to pulverize and corrode. It is necessary to adjust their chemical composition and adopt surface treatment methods to improve them. Claim. Of course, the advantages of high energy density make NdFeB permanent magnet materials widely used in modern industrial and electronic technology.

 

It can be seen that the high-performance permanent magnet ferrite magnet has very good stability. It is an oxide itself, very stable, and NdFeB is an alloy, and its simple oxidation requires maintenance of the coating.
