China Neodymium And Ferrite Magnets Manufacturer & Supplier 
I have introduced about N35 VS N38 Grade Neodymium Magnets in previous articles, and today I mainly introduce the specific difference between N42 VS N45 grade neodymium strong magnets, Including magnetic strength, price, uses, gauss and other aspects of comparison..
The difference of magnetic strength between N42 and N45 grade neodymium magnets;
N45 magnets have a higher magnetic field strength than N42 grade neodymium magnets, which means that under the same conditions, N45 magnets can produce a stronger magnetic field than N42 magnets, depending on the specific magnet size, shape and manufacturing process and other factors.
It can also be seen from their respective magnetic energy products; maximum energy product standard of N42 material is 40 ~ 43MGOe, and the maximum energy product standard of N45 material is 43 ~ 46MGOe.

The price difference between N42 and N45 grade;
In general, N45 magnets of the same size and shape are more expensive than N42 magnets, because N45 materials are more expensive.
Is N42 4200 Gauss and N45 4500 Gauss?
Not really. N42, N45 is the grade of the magnet material, 4200gs, 4500GS is the size of the magnetic field calculated according to your grade and magnet size, usually the larger the magnet area, the surface magnetic dispersion will be lower.
If you want to calculate the surface magnetism of a magnet, you can try using the neodymium magnet surface Gaussian calculation tool.
Choose N42 grade or N45 grade rare earth neodymium magnets?
If your application requires stronger magnetic field strength, such as for motors, generators, sensors, or magnetic adsorption, then N45 grade magnets may be more suitable because they have stronger magnetism and can be processed in smaller sizes.
Some special environments may have high requirements for the performance and stability of magnets, such as high temperatures, corrosive environments, or strong magnetic field environments. In this case, you should choose a magnet with a suitable coating, packaging, or treatment that adapts to the desired environment, and the magnetic strength level itself (such as N42 or N45) may not be the determining factor.
The above is the difference between N42 grade and N45 grade neodymium strong magnets. If you have any questions or need to purchase rare earth strong magnets from us, you can communicate with us through the contact information on the right side of the website.
