NdFeB Magnets Vs Ordinary Magnets (Detailed Guide)

Zhaobao Magnet

The key difference between Neodymium magnet and Regular Magnet is that the neodymium magnet contains neodymium, iron, and boron as the key chemical elements whereas the regular magnet contains iron as the key chemical element.So what are the differences between them? let's figure it out together!

What is Neodymium Magnet?

A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is the most widely used type of rare-earth magnet. It is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. Neodymium magnets are the strongest type of permanent magnet available commercially.

 

What is Ordinary Magnet?

Regular magnets are the magnets that we use for regular purposes. Most of the times, we use ceramic (or ferrite) magnets as regular magnets. These magnets contain ferrite as the major component. Ferrite is a ceramic material. It mainly consists of iron(III) oxide. We blend this compound with some other metals such as barium, manganese, nickel and zinc. These components are ferromagnetic and electrically non-conductive.

 

The Difference Between NdFeB Magnets and Ordinary Magnets

1. NdFeB strong magnets have good resistance: ordinary magnets will continuously demagnetize and demagnetize in the air. Strong magnets are mainly made of rare elements, and they have high coercivity. In the natural environment and normal conditions, they cannot affect their magnetic force at all, ensuring the stability of the magnetic force. Different from the exposed magnet, the electroplating on the surface of the NdFeB strong magnet can ensure that the magnet is not corroded by substances such as acid and alkali.

 

2. NdFeB strong magnets have high temperature resistance: the extreme temperature and Curie temperature of strong magnets are stronger than ordinary magnets. Regardless of the material used for the strong magnet, it is superior to the magnet, so the limit temperature that the magnet itself can withstand is greatly increased, and the machine can be guaranteed to run at the temperature used by the machine.

 

3. NdFeB strong magnets are hard: the strong magnets have added the density of rare elements, making the magnets much harder than ordinary magnets. The collisions that cannot be avoided during use will not affect the integrity of the magnet. The general magnetite is fragile and cannot maintain its appearance for a long time. Fine precision: strong magnets have good meticulousness. Whether it is size tolerance or performance magnetic force value, there are professional machines such as Gauss meter to measure, indicating the direction of magnetization, so that the error can be ignored, while ordinary magnet products have rough production process, for Other errors are not calculated at all, which greatly reduces the functionality that is already available.

 

4. Strong practicability and preservation of NdFeB magnets: The strength of NdFeB strong magnets is not only better than ordinary magnets in performance, but also more practical than ordinary magnets, which can meet the special needs of various customers. need. And the preservation is better than ordinary magnets. Ordinary magnets cannot be used for a long time at all, while the preservation of strong magnets is complete and suitable for large-scale inventory in various situations.
